STARTING UP AND ADJUSTMENT

The welding gas which is used must correspond to the welding ap-

plication case. The table below shows the main cases and gases

which can be used with solid wires.

Key: +++ = very good, ++ = good, + = average

(1) product quality: homogeneity, control of impurities, traceability

7.0 STARTING UP AND ADJUSTMENT

The main ON/OFF switch is located on the

front panel of the power-source. This switch is

used to start the unit up.

The green indicator lamp shows that the power-source

is operating.

The yellow indicator lamp indicates an operating de-

fect :

- Over heating of the power source

- Missing phase on power supply

- water safety

7.1 WELDING CYCLES SELECTION

In MIG-MAG welding, pressing the trigger of the MIG torch has dif-

ferent effects, depending on the cycle or welding method used.

The cycle is selected by means of the buttons located on the front

panel of the power source, on the top area.

2 - action cycle

Pressing the trigger

causes the wire feed, the

pregas and the establish-

ment of the welding cur-

rent. When the trigger is

released, welding stops.

4 - action cycle

without crater-filler

PRE-GAS is activat-

ed the first time the

trigger is pressed.

When the trigger is

released, welding

starts up (wire feed

+ current). Pressing

the trigger again

stops the welding

but the gas contin-

ues to flow. Releas-

ing the trigger a final

time stops the

POST-GAS.

4 - action with cra-

ter filler cycle

This mode is the

same as previous

one except for the

end of the weld. It

can be finished with

a low level welding

phase. This contin-

ues whenever the

trigger is pressed.

Then comes the

post gas time.

7.2 WIRE AND GAS SELECTION

The three switches below on the front panel are used for:

1. gas selection (CO2or mix gases Ar + CO2 etc...)

2. wire type selection:

- Solid W = solid wire

- FCW = cored wire

- Fe = steel wire

- Cr Ni = stainless steel wire

- Alu = aluminium wire

3. wire diameter.

Welding with cored steel wire, diameter 1.2mm using mixed gas

will be carried out by selecting MIX - FCW - Fe - 1.2.

Once this selection has been made, the 'OPTI' System integrated

in the power source will preset the voltage adjustment.

Therefore, one has only to position the blue button on the

wire-feed unit in the middle position in order to have an arc

voltage adjustment adapted to the selected wire speed ad-

justment (red button).

COMMENT: THE FCW - ALU POSITION DOES NOT HAVE A

SPECIAL PRE-SETTING; IT PROVIDES ACCESS TO THE EN-

TIRE VOLTAGE ADJUSTMENT RANGE OF THE POWER

SOURCE ("OPEN" SYNERGY).

7.3 WELDING PARAMETERS ADJUSTMENT

Two buttons on the wire feed unit permit the adjustment of the wire

speed and the welding voltage.

1. The upper button (red) adjusts the wire speed from 1m/mn up

to approx. 20m/mn.

2. The lower button (blue) adjusts the welding voltage and then

the arc length.

OPTI'SYSTEM

As told above, to make this last adjustment easier and more fine,

the adjustment range, available with the blue button, is optimised

depending on gas, wire type and diameter. The middle position of

the button indicates an average value corresponding to the gen-

eral use of the wire/gas used.It's the enough to fine tune the ad-

justment around this middle position.Some applications or some

welding positions may need a more specialised adjustment, farest

from the middle position of the blue button.

DISPLAYS

These enable:

1. either pre-display: signal lamp off

2. or display of the measured values: signal lamp on of the

welding parameters. The signal lamp stays on 10s after weld-

ing (les valeurs de tension et de courant sont mémorisés

pendant 10s après la fin du soudage).

Depending on the position of the selector switch, the top display

unit enables the display of:

- the welding current in amperes

- the thickness of the material to be welded

- the welding wire feed speed in meters per minute.

The lower display unit shows the welding voltage in volts. The ac-

curacy of the display units is:

- 6% ±0.2V for the voltage display unit

- 6.5% ±2A for the current display unit

OTHERS PARAMETERS:

the values preset in the plant for pre-gas and post-gas and burn-

back control are

7.4 INTERNAL ADJUSTMENTS

Although striking voltage,Pre-gas, Post-gas and burn back values

should be changed.

1. Adjustment of striking voltage from -4 to +6

2. Pre gas adjustment from 0 to 10s

3. Post gas adjustment from 0 to 10s

4. Post retract adjustment from 0 to 100

PRE-GAS, POST-GAS and POST-RETRACT (also called "burn

back") duration are adjustable on the PC board, inside the power

source unit. Adjustment ranges:

PRE-GAZ = 0 - 10s

POST-GAZ = 0 - 10s

The post-retract operates at a fixed time (100 ms) and the adjust-

ment sets the voltage applied during this post-retract time. This

voltage is adjustable from the minimum to maximum voltage of the

power-source.

ALTHOUGH IT'S BETTER TO MODIFY THOSE ADJUSTMENT

ONLY IN CASE OF ABSOLUTE NECESSITY.

8.0 MAINTENANCE

Twice a year, according to how often the set is used, inspect:

1. the general cleanliness of the power source

2. the electrical and gas connections.

CAUTION: NEVER CLEAN OR MAKE REPAIRS ON THE IN-

SIDE OF THE SET WITHOUT FIRST MAKING SURE THAT THE

SET HAS BEEN DISCONNECTED FROM THE MAINS.

Remove the power source panels and vacuum up any dust

and particles which have accumulated between the magnetic

circuits and the transformer windings. Always fit a plastic

nozzle when cleaning these parts so as not to damage the

winding insulation.

CAUTION: TWICE A YEAR

CAREFULLY VACUUM THE ELECTRONIC CIRCUITS, TAK-

ING CARE TO ENSURE THAT THE NOZZLE DOES NOT DAM-

AGE THE COMPONENTS.

If the power source develops a malfunction, before trying to

diagnose the problem, perform the following steps, check:

1. the electrical connections on the power, control and supply

circuits.

2. the condition of the insulation, cables and lines.

CAUTION: AT EACH STARTUP OF THE WELDING SET AND

BEFORE ANY SAV TECHNICAL SERVICING OPERATIONS,

CHECK:

1. that power terminals are not poorly tightened

2. that the coupling is right

3. the gas flow

4. the condition of the torch

5. the kind and diameter of the wire

6. the connection of the cooling unit earth clamp and that the 2-

way circuit-breaker has tripped
