SAFETY

These general safety norms cover both arc welding machines and plasma cung machines unless

otherwise noted.

The equipment must only be used for the purpose it was designed for. Using it in any other way could

result in damage or injury and in breach of the safety rules.

Only suitably trained and competent persons should use the equipment. Operators should respect the

safety of other persons.

Prevenon against electric shock

The equipment should be installed by a qualied person and in accordance with current standards in

operaon. It is the users responsibility to ensure that the equipment is connected to a suitable power

supply. Consult with your ulity supplier if required

If earth grounding of the work piece is required, ground it directly with a separate cable.

Do not use the equipment with the covers removed.

Do not touch live electrical parts or parts which are

electrically charged.

Turn o all equipment when not in use.

Cables (both primary supply and welding) should be

regularly checked for damage and overheang. Do not use worn, damaged, under sized, or poorly

jointed cables.

Ensure that you wear the correct protecve clothing, gloves, head and eye protecon.

Insulate yourself from work and ground using dry insulang mats or covers big enough to prevent any

physical contact with the work ground.

Never touch the electrode if you are in contact with the work ground, or another electrode from a

dierent machine.

Do not wrap cables over your body.

Ensure that you take addional safety precauons when you are welding in electrically hazardous

condions such as damp environments, wearing wet clothing, and metal structures. Try to avoid

welding in cramped or restricted posions.

Ensure that the equipment is well maintained. Repair or replace damaged or defecve parts

immediately. Carry out any regular maintenance in accordance with the manufacturers instrucons.

Safety against fumes and welding gases

Locate the equipment in a well-venlated posion.

Keep your head out of the fumes. Do not breathe the fumes.

Ensure the welding zone is in a well-venlated area. If this is not possible provision should be made for

suitable fume extracon.

A WILKINSON STAR LIMITED PRODUCT 12-16 ISSUE 1

If venlaon is poor, wear an approved respirator.

Read and understand the Material Safety Data Sheets (MSDS’s) and the manufacturer’s instrucons for

metals, consumable, coangs, cleaners, and de-greasers.

Do not weld in locaons near any de-greasing, cleaning, or spraying operaons. Be aware that heat and

rays of the arc can react with vapours to form highly toxic and irritang gases.

Do not weld on coated metals, unless the coang is removed from the weld area, the area is well

venlated, and while wearing an air-supplied respirator. The coangs on many metals can give o toxic

fumes if welded.

Prevenon against burns and radiaon

Arc rays from the welding process produce intense, visible and invisible (ultraviolet and infrared) rays

that can burn eyes and skin.

Wear an approved welding helmet ed with a proper shade of lter lens to protect your face and eyes

when welding or watching.

Wear approved safety glasses with side shields under your helmet.

Never use broken or faulty welding helmets.

Always ensure there are adequate protecve screens or barriers to protect others from ash, glare and

sparks from the welding area. Ensure that there are adequate warnings that welding or cung is taking

place.

Wear suitable protecve ame resistant clothing.

The sparks and spaer from welding, hot work pieces, and hot equipment can cause res and burns

Welding on closed containers, such as tanks, drums, or pipes, can cause them to explode.

Accidental contact of electrode to metal objects can cause arcs, explosion, overheang, or re.

Check and be sure the area is safe and clear of inammable material before carrying out any welding.

Protecon against noise

Some welding and cung operaons may produce noise.

Wear safety ear protecon to protect your hearing.

Protecon from moving parts

When the machine is in operaon keep away from moving parts such as motors and fans. Moving parts,

such as the fan, may cut ngers and hands and snag garments.

Protecons and coverings may be removed for maintenance and controls only by qualied personnel,

aer rst disconnecng the power supply cable.

Replace the coverings and protecons and close all doors when the intervenon is nished, and before

starng the equipment.

Take care to avoid geng ngers trapped when loading and feeding wire during set up and operaon.

When feeding wire be careful to avoid poinng it at other people or toward your body.

A WILKINSON STAR LIMITED PRODUCT 12-16 ISSUE 1

Always ensure machine covers and protecve devices are in operaon.

Precauons against re and explosion

Avoid causing res due to sparks and hot waste or molten metal

Ensure that appropriate re safety devices are available near the cung / welding area.

Remove all ammable and combusble materials from the cung / welding zone and surrounding areas

Do not cut/weld fuel and lubricant containers, even if empty.

These must be carefully cleaned before they can be cut/ welded.

Always allow the cut/welded material to cool before touching it or placing it in contact with combusble

or ammable material.

Do not work in atmospheres with high concentraons of combusble fumes, ammable gases and dust.

Always check the work area half an hour aer cung to make sure that no res have begun.

Risks due to magnec elds

The magnec elds created by high currents may aect the operaon of pacemakers or electronically

controlled medical equipment.

Wearers of vital electronic equipment should consult their physician before beginning any arc welding,

cung, gouging or spot welding operaons.

Do not go near welding equipment with any sensive electronic equipment as the magnec elds may

cause damage.

RF Declaraon

Equipment that complies with direcve 2004/108/EC concerning electromagnec compability (EMC)

and the technical requirements of EN60974-10 is designed for use in industrial buildings and not those for

domesc use where electricity is provided via the low voltage public distribuon system. Dicules may

arise in assuring class A electromagnec compability for systems installed in domesc locaons due to

conducted and radiated emissions.

In the case of electromagnec problems, it is the responsibility of the user to resolve the situaon. It may

be necessary to shield the equipment and t suitable lters on the mains supply.

LF Declaraon

Consult the data plate on the equipment for the power supply requirements.

Due to the elevated absorbance of the primary current from the power supply network, high power

systems aect the quality of power provided by the network. Consequently, connecon restricons or

maximum impedance requirements permied by the network at the public network connecon point

must be applied to these systems.

In this case the installer or the user is responsible for ensuring the equipment can be connected,

consulng the electricity provider if necessary.

Materials and their disposal

The equipment is manufactured with materials, which do not contain any toxic or poisonous materials

A WILKINSON STAR LIMITED PRODUCT 12-16 ISSUE 1

dangerous to the operator.

When the equipment is scrapped, it should be dismantled separang components according to the

type of materials.

Do not dispose of the equipment with normal waste. The European Direcve 2002/96/EC on Waste

Electrical and Electronic Equipment states the electrical equipment that has reached its end of life must

be collected separately and returned to an environmentally compable recycling facility.

Handling of Compressed gas cylinders and regulators

All cylinders and pressure regulators used in welding operaons should be handled with care.

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.

Always secure the cylinder safely

Never deface or alter any cylinder

Funcons and characteriscs of the cung machine

Advanced digital control mode

The Plasma cung machines JP 61/81 MUC intelligent digital control technology, and all its major

funcons are performed using soware controls. The digital control plasma cung machine oers

many improvements in funcon and performance when compared with the tradional type plasma

cung machines.

With PWM technology and high power component IGBTs, it inverts the DC voltage, which is reced

from 50Hz/60Hz input AC voltage, to 30K~50KHz AC high voltage. The voltage is dropped and reced

to output the DC power supply for cung. This inverter technology provides a machine which is smaller

and much less weight than the tradional style machine. The technology provides a high eciency unit

and the switching frequency is outside the audible range.

Good consistency and stable performance

In tradional machines consistency and performance is oen governed by the tolerances of the

components used in manufacture and environmental such as temperature and humidity. In some cases

the same machine brand and type can vary in performance due to tolerance dierences. One of the

characteriscs of digital control is that it is not sensive to the change of these parameters. The

performance of cung machine will not be aected by the change of the parameters of individual

parts. Therefore, the consistency and stability of performance of the digital control cuer is beer than

that of tradional cuer.

Powerful cung performance

These machines provide economical cung of metals using compressed air as the plasma gas source.

The cung speed is 1.8 mes when compared with oxyacetylene cung. The machines can cut steel, s

stainless steel, copper, cast iron and aluminium easily and quickly. The arc is easy to ignite arc and uses

a non HF arc ignion mode. There is a post-ow funcon operates to cool the torch aer cung. The

simple operaon and high cung speed, smooth cung surface make the plasma process and

excellent cung method.
