11. TROUBLESHOOTING
Error Cause Remedy
The machine stopped to
weld suddenly
– the fan is
running and the
temperature indicator is lit
up
Over-temperature in electric-circuit
–
the yellow indicator is lit up
Allow the machine to cool down, until the
temperature indicator is lit out
DON`T SHOT OFF THE MACHINE WHILE
COOLING!
The mains switch is
turned on, but the
machine doesn`t work
Phase failure
Check mains fuse protection, mains supply
lead and mains plug
There is no contact between mass
clamp and work piece Ensure a tight connection between mass
clamp and work piece
The power transformer is damaged Check/replace the transformer
The switch is damaged Check/replace the switch
Incontinous, week or bad
arc
Poor contact between the mass clamp
and the work piece Clean the point of contact, check and
tighten the earthening connection
Incorrect welding current selected
Select the appropriate welding current
(refer to this operating instruction)
No welding current. Mains
switch is ON and
indicators are lit up
Earth connection is wrong
Check the earth connection and clamp for
correct polarity
Break in the current cable in the
welding torch
Exchange the torch
Machine does not function
when the torch trigger is
pressed. Mains switch is
ON and indicators are lit
up. Welding torch/torch control lead
defective
Exchange the torch
Interconnecting cable defective or not
connected up properly
Check interconnecting cable.
No shielding gas. All other
functions are OK.
Gas cylinder is empty. Change the gas cylinder
Gas pressure regulator is faulty. Change the gas pressure regulator
Gas hose is not mounted or is
damaged
Mount/change the gas hose
Welding torch is defective Change the welding torch
Gas solenoid valve is defective Change the gas solenoid valve
Poor welding properties
Wrong welding parameters Check settings
Poor earth connection Ensure good contact to work piece
Not enough shielding gas, or none at
all
Check the pressure regulator, gas hose,
gas solenoid valve, torch gas connection
etc
Welding torch is leaking Change the torch
Wrong contact tube, or contact tube is
worn out
Change the contact tube
Wrong wire alloy and/or wrong wire
diameter
Check the wire spool
Check the weldability of the base metal
Shielding gas is not suitable for this
wire alloy
Use the correct shielding gas
Irregular wire feed.
Welding wire forms a loop
between the feed rollers
and the wire inlet nozzle
of the welding torch
Braking force is set too high Loosen the brake
Contact tube is too narrow Use a suitable contact tube
Wirefeeder inner liner in the welding
torch is defective
Check the wire inner liner for kinks, dirt, etc
Wirefeed rollers are unsuitable for the
wire being used
Use suitable wirefeed rollers
Wirefeed rollers have wrong contact
pressure
Optimise the contact pressure
Insufficient cooling power. Fan is defective Replace the fan
