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.
The machine does not deliver any
current and the thermal overload
indicator lamp lights up.
The display is on but the device
does not deliver any current.
If, when the unit is on and you
put your hand on the welding
unit's body, you feel tingling
sensation.
The display is on but the device
does not deliver any current.
When starting up, the display
indicates .
Instable arc
The tungsten electrode
oxidised and tern at the end of
welding.
The electrode melts
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.
The welder thermal protection has
turned on.
The cable of the earth clamp or
electrode holder is not connected to
the welder.
The welding unit is not correctly
connected to the earth.
The cable of the earth clamp or
electrode holder is not connected to
the welder.
The input voltage is outside of
the range (230V + 15% for single
phase or 400V + 15% for 3-phase).
Default coming from the tungsten
electrode
Too important gas flow rate
Welding zone
gets
Default coming from post-gas or the
gas has been stopped prematurely.
Polarity error
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.
Wait for the end of the cooling time, around 2
minutes. The indicator lamp turns off.
Check the connections.
Check the plug and the earth of your electrical
network.
Check the connections.
Have the electrical installation checked.
Use a tungsten electrode with the adequate size
Use a well prepared tungsten electrode
Reduce gas flow rate
Protect welding zone against air flows
Check and tighten all gas connections. Wait until
the electrode cools down before stopping the gas.
Check that the earth clamp is really connected to +
