Possible Causes - GYS MULTIPEARL 210-2 Mode D'emploi

Translation of the original instructions
DUTY CYCLE AND WELDING ENVIRONMENT
• The machine has a specification with a "dropping current output" (MMA & TIG). The machine has a specification with a "constant
current output" (MIG). Its duty cycle following the norm EN60974-1 is indicated in the table below :
X / 60974-1 @ 40°C (T cycle = 10 min)
MIG-MAG
MMA
TIG
MIG-MAG
MMA
TIG
THERMAL PROTECTION AND GUIDANCE
While under intensive use (superior to the duty cycle) the thermal protection can activate, in that case, the arc switches off and the
thermal protection indicator switches on.
• Ensure the machine's vents are clear enabling air circulation.
• Leave the device plugged in after welding to enable cooling.
In general :
• Respect the basic rules of welding.
• Ensure the air circulation is good.
• Do not work in a wet area.
TROUBLESHOOTING
SYMPTOMS
The welding wire speed is not
constant.
The unwinding motor doesn't
operate.
Bad wire unwinding.
No welding current
The wire rubs down after the
rollers.
The welding cord is porous
Very important flashing particules.
No gas at the torch output.

POSSIBLE CAUSES

Cracklings block up the opening.
The wire skids in the rollers.
Reel or roller brake too tight.
Electrical supply problem.
Covering wire guide dirty or
damaged.
Reel brake too tight
Bad connection to the main supply.
Bad earth connection.
Power contactor inoperative.
Covering wire guide crushed.
Locking of the wire in the torch
No capillary tube.
Wire speed too fast
The gas flow rate is not sufficient.
Gas bottle empty.
Gas quality non-satisfying.
Air flow or wind influence.
Gas nozzle too full.
Bad wire quality.
Surface to weld in bad condtion.
(rust, etc, ...)
Arc voltage too low or too high.
Bad earth connection.
Protecting gas insufficient.
Bad gas connection.

REMEDIES
Clean out the contact batch or change it and
replace the anti-adherence product. Ref.041806
Control the roller pressure or replace it.
Wire diameter non-consonant with roller.
Covering Wire guide in the torch non-consonant.
Release the brake and rollers.
Check that the running button is on the position
on.
Clean or replace
Release the brake
See the branch connection and look if the plug is
fed by 3 phases.
Control the earth cable (connection and clamp
condition).
Control the torch trigger.
Check the covering and torch body.
Clean or replace.
Check the presence of capillary tube.
Reduce the wire speed
Adjusting flow range 15 to 20 L / min. Clean the
working metal.
Replace it.
Replace it.
Avert air blast, protect welding area.
Clean or replace the gas nozzle.
Use adapted WIRE for MIG-MAG welding.
Clean the working parts before welding.
See welding settings.
Check and place the earth cable to have a better
connection.
Adjust the gas flow.
See if the gas coupling beside the engine is well
connected. Check the flowmeter and the solenoid
valves.
