CUTTING & WELDING TECHNOLOGIES

2/68

ARCONTROL are welding machines for MMA arc welding that can also perform TIG operations. They adopt the latest

Pulse Width Modulation (PWM) technology and the Insulated Gate Bipolar Transistor (IGBT) power module. They are

equipped with some automatic protection functions for undervoltage, overcurrent, overheating, etc. that prolong their

lifetime and greatly improve their reliability and practicality.

Read and understand all instructions before using.

Arc welding produces intense electric and magnetic emissions that may interfere with the proper function of cardiac

pacemakers, hearing aids, or other electronic health equipment. Persons who work near arc welding applications should

consult their medical health professional and the manufacturer of the health equipment to determine whether a hazard

exists. To prevent possible injury, read, understand, and follow all warnings, safety precautions and instructions before

using the equipment.

Only qualified persons should install, operate, maintain, and repair this equipment.

During the operation, non-concerned people should not be present, especially children.

Contact with live electrical parts can cause fatal shocks or severe burns. The electrode and the work circuit are

electrically live whenever the output is on. The input power circuit and the internal circuits of the machine are also active

when power is on. The equipment installed incorrectly or improperly grounded is dangerous.

Never touch electrical parts.

Wear dry, hole-free gloves and clothes to insulate yourself.

Insulate yourself from workpiece and ground using dry insulation. Make sure the insulation is large enough to cover

your full area of physical contact with workpiece and ground.

Be careful when using the equipment in a tight place, or when there's a risk of fall and moisture.

Make sure to install the equipment correctly and ground the work or metal to be welded to a good electrical (earth)

ground according to the operation manual.

The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts

with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate your hands.

Always make sure the work cable makes a good electrical connection with the metal being welded. The connection

should be as close as possible to the area being welded.

Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating condition.

Replace damaged insulation.

Never dip the electrode in water for cooling.

Never simultaneously touch electrically “hot” parts of electrode holders connected to two different welders because

voltage between the two can be the total of the open circuit voltage of both welders.

When working above floor level, use a safety belt to protect yourself from a fall in case of shock.

Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. When welding,

keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from

the breathing zone. When welding with electrodes which require special ventilation such as stainless or hard facing or

on lead or cadmium plated steel and other metals or coatings which produce highly toxic fumes, keep exposure as low

as possible and below Threshold Limit Values using local exhaust or mechanical ventilation. In confined spaces or in

some circumstances, outdoors, a respirator may be required. Additional precautions are also required when welding

on galvanized steel.

Do not weld in locations near chlorinated hydrocarbon vapours coming from degreasing, cleaning, or spraying

operations. The heat and rays of the arc can react with solvent vapours to form phosgene, a highly toxic gas, and

other irritating products.

Shielding gases used for arc welding can displace air and cause injury or death. Always use enough ventilation,

especially in confined areas, to ensure breathing air is safe.

Read and understand the manufacturer’s instructions for this equipment and the consumables to be used, including

the material safety data sheet and follow your employer’s safety practices.

3/68

Arc rays from the welding process produce intense visible and invisible ultraviolet and infrared rays that can burn eyes

and skin.

Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when

welding or observing open arc welding.

Use suitable clothing made from durable flame-resistant material to protect your skin and that of your helpers from the

arc rays.

Protect other nearby personnel with suitable, non-flammable screening and /or warn them not to watch the arc nor

expose themselves to the arc rays or to hot spatter or metal.

Welding on closed containers, such as tanks, drums, or pipes, can make them explode. Flying sparks from the welding

arc, hot workpiece, and hot equipment can cause fires and burns. Accidental contact of electrode to metal objects can

cause sparks, explosion, overheating, or fire. Check and be sure the area is safe before making any welding.

Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from

starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and

openings to adjacent areas. Avoid welding near hydraulic lines. Have a fire extinguisher easily available.

Where compressed gases are to be used at the job site, special precautions should be used to prevent hazardous

situation.

When not welding, make sure that no part of the electrode circuit is touching the work or ground. Accidental contact

can cause overheating and create a fire hazard.

Do not heat, cut, or weld tanks, drums or containers until the proper steps have been taken to ensure that such

procedures will not cause flammable or toxic vapours from substances inside. They can cause an explosion even

though they have been cleaned.

Vent hollow castings or containers before heating, cutting, or welding. They may explode.

Sparks and spatter are thrown from the welding arc. Wear oil free protective garments such as leather gloves, heavy

shirt, cuff less trousers, high shoes, and a cap over your hair. Wear ear plugs when welding out of position or in

confined places. Always wear safety glasses with side shields when in a welding area.

Connect the work cable to the work as close to the welding area. Work cables connected to the building framework or

other locations away from the welding area increase the possibility of the welding current passing through lifting

chains, crane cables or other alternate circuits. This can create fire hazards or overheat lifting chains or cables until

they fail.

DO NOT refuel near an open flame welding arc or when the engine is running. Stop the engine and allow it to

cool before refuelling to prevent spilled fuel from vaporizing on contact with hot engine parts and igniting. Do

not spill fuel when filling tank. If fuel is spilled, wipe it up and do not start engine until fumes have been

eliminated.

Keep all equipment safety guards, covers and devices in position and in good repair. Keep hands, hair, clothing, and

tools away from V-belts, gears, fans, and all other moving parts when starting, operating, or repairing equipment.

Do not put your hands near the engine fan.

Use only compressed gas cylinders containing the correct shielding gas for the process used and properly operating

regulators designed for the gas and pressure used. All hoses, fittings, etc. should be suitable for the application and

maintained in good condition.

Always keep cylinders in an upright position securely chained to an undercarriage or fixed support.

Cylinders should be located:

Away from areas where they may be struck or subjected to physical damage.

A safe distance from arc welding or cutting operations and any other source of heat, sparks, or flame.

Never allow the electrode, electrode holder or any other electrically “hot” parts to touch a cylinder.

Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.

Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for

use.

Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). The discuss on the

effect of EMF is ongoing all the world. Up to now, no material evidences show that EMF may have effects on health.

However, the research on damage of EMF is still ongoing. Before any conclusion, we should minimize exposure to EMF

as few as possible. In order to minimize EMF, we should use the following procedures:

Route the electrode and work cables together – Secure them with tape when possible.

All cables should be put away and far from the operator.

Never coil the power cable around your body.

4/68

Make sure welding machine and power cable to be far away from the operator as far as possible according to the

actual circumstance.

Connect the work cable to the workpiece as close as possible to the area being welded.

People with heart-pacemaker should be away from the welding arc.

ARCONTROL are welding machines for MMA arc welding which adopts the latest Pulse Width Modulation (PWM)

technology and the Insulated Gate Bipolar Transistor (IGBT) power module. It can change work frequency to medium

frequency to replace the traditional hulking work frequency transformer with the cabinet medium frequency transformer.

Thus, the welding machine is featured by portability, small size, low consumption, etc.

ARCONTROL welding machines have excellent performances: constant current output makes welding arc more stable;

fast dynamic response speed reduces the impact from the arc length fluctuation to the current; accurate stepless current

adjustment and pre-setting function. There are also some automatic protection functions for under voltage, over current,

over heat, etc. inside the welders, when the problems listed before occurred, the alarm on the front panel is light and at

the same time the output current will be cut off. It can self-protect and prolong the using life and greatly improved the

reliability and practicability of the welders.

ARCONTROL welding machines can also realize TIG operation. While MMA operation, if the electrode touches work

piece over two seconds, the welding current will drop to the minimum current automatically to protect the electrode. While

TIG operation, the minimum current will be outputted firstly until the arc is ignited by lifting method, the output current will

rise to the pre-set value, which can protect the electrode.

Built-in extra functions

"Hot Start" function for easier arc striking.

"Arc Force" to prevent electrode sticking to the workpiece. Smoother welding and deeper penetration.

"Anti-sticking" device to prevent overload and ease the electrode removal from the workpiece.

Fully protected against over-voltage, under-voltage, and over-heat.

Generator friendly. Designed to work with diesel generators and to avoid failures due to its voltage spikes.

The above parameters are subject to change with the improvement of machines.

The working principle of ARCONTROL (See Pic. 1 at the end of this manual).

The single-phase 230 V alternating current with 50/60 Hz working frequency is rectified into direct current (about 312V),

then it is converted into a medium frequency alternating current (about 50 KHz) by the inverter device (IGBT module).

The voltage is then reduced by the medium transformer (the main transformer) and rectified by the medium frequency

rectifier (fast recovery diodes) and is then outputted by inductance filtering. The circuit adopts the current feedback

control technology to ensure the stability of the current output. In this way the welding current parameter can be set by a

stepless adjustment to better meet the welding requirements.

ARCONTROL welding machines have excellent volt-ampere characteristic (See Pic. 2 at the end of this manual).

In MMA welding, the relation between the rated loading voltage U2 and welding current I2 is as follows:

See Pic. 3 at the end of this manual

Manual Metal Arc welding (MMA)

The choice of connecting the electrode to the Positive (DCEP) or Negative (DCEN) polarity depends on the type of

electrode. The different electrodes must be connected differently. Please refer to the electrode manual.

See Pic. 4 at the end of this manual

Connect the electrode lead and the earth lead to the proper output and tighten clockwise.

Ensure good contact and prevent oxidation.

Check the input voltage is within the range by measuring with a multimeter.

Tungsten Inert Gas Welding (TIG)

For TIG welding operations the TIG torch must be connected to the Negative polarity (DCEN) while the ground cable to

the Positive polarity.

During TIG operation, the shielding gas is fed directly into the welding torch, and the "lifting arc" striking method must be

adopted.

See Pic. 5 at the end of this manual

Connect the torch cable and the grounding cable to the proper output and tighten clockwise.

Ensure good contact and prevent oxidation.

Check the input voltage is within the range by measuring with a multimeter.

Turn the power switch to the “ON” position. The power indicator on the front panel lights up, the fan turns on, the

device is working properly.

Select the welding mode according to your welding method by switching the mode selector (MMA or TIG).

ARCONTROL welding machines have the function of welding current pre-setting. Before welding, adjusting welding

current, the welding current display will show the ampere. It is convenient to set parameters and adjust accurately.

In MMA welding set the welding current relevant to the electrode type and size being used as recommended by the

electrode manufacturer.

In TIG welding set the welding current relevant to the electrode type and size being used according to standard ISO 6848.

Manual Metal Arc welding (MMA)

See Pic. 6 at the end of this manual

Tapping technique: Hold the electrode upright and touch the workpiece. After forming a short circuit, quickly lift up

about 2~4 mm, and arc will be ignited. This method is difficult to master. But in welding brittle or hard steel, it is better

to use knocking way.

Take the electrode upright

The Electrode touch the workpiece

Lift up for about 2-4mm

Scratching technique: Hold the electrode and scrape the workpiece to strike the arc. This method can cause

scratches, so it is advisable to use it into the groove.

Hold the electrode inclined at an angle.

Scrape the workpiece with the electrode and strike the arc

Lift up for about 2-4mm

Tungsten Inert Gas Welding (TIG)

When tungsten electrode touches the workpiece, the short-circuit current is 100A. After generating arc, current turn to the

setting welding current. If the tungsten electrode touches the workpiece when welding, the current will drop to 30A within

1s, which can reduce the tungsten spoilage significantly, prolong the using life of the tungsten electrode, and prevent

tungsten clipping.

See Pic. 7 at the end of this manual

TIG Lift: Place the welding gun aslant.

Scrape the workpiece with the electrode.

Lift arc.

Complete the operations.

After welding is completed, the power supply should be left ON for 2 to 3 minutes. This allows the fan to cool the internal

components.

Switch the ON/OFF Switch (located on the rear panel) to the OFF position and turn off the machine.

Height above sea level is below 1000m.

Operation temperature range: -10°C~+40°C.

Relative humidity is below 90% (+20°C).

Preferably place the machine at an angle not exceeding 15° compared to the floor level.

Protect the machine against heavy rain or in hot circumstance against direct sunshine.

The content of dust, acid, corrosive gas in the surrounding air or substance cannot exceed normal standard.

Take care that there is sufficient ventilation during welding. There is at least 30cm free distance between the machine

and wall.

The input power must be in AC single phase, 50Hz, 220/230V. Do not operate in case of phase failure.

In case closing the power switch, no-load voltage may be exported. Do not touch the output electrode with any part of

your body.

7/68

When power switch shuts off protectively because of failure, do not restart the unit until problem is solved. Otherwise,

the range of problem will be extended.

Note the polarity of wiring. Select the appropriate connections based on the welding technical requirements. An

incorrect choice will result in arc instability, increase in spatters and other phenomena.

If the workpiece is very far from the welding machine, the use of longer cables (electrode holder and ground) may

result in a voltage drop. In this case it is necessary to use cables with a larger cross-section.

The duty cycle is defined as the proportion of time that a machine can work continuously within a certain time lapse

(10 minutes). The rated duty cycle means the proportion of time that a machine can work continuously within 10

minutes when it outputs the rated welding current. If the welding machine overheats, the IGBT overheat protection unit

inside cuts the output welding current, and the overheat pilot lamp on the front panel lights up. At this point, the

machine should be left to stand for 15 minutes so that the fan can cool it. When operating the machine again, the

welding output current or the duty cycle should be reduced.

The electrode should be dried before use to reduce the presence of hydrogen in the molten pool and the welding bead

and to avoid blowhole and cold cracks.

In the welding process, the arc should not be too long, otherwise it would cause unstable arc burning, a wider area of

spatters, poor penetration, undercut, blowhole, etc. If the arc is too short, this will cause electrode sticking.
