Poor welding properties Wrong welding parameters Check settings
Poor earth connection Ensure good contact to workpiece
Not enough shielding gas, or none at all Check pressure regulator, gas hose,
gas solenoid valve, torch gas connec-
tion 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 dia-
meter
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 wirefeed
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
Wirefeed 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 pres-
sure
Optimise the contact pressure
Control plug is not plugged in Plug in the control plugMachine does not function when the
torch trigger is pressed
Mains switch is ON and indicators are
lit up
Earth connection is wrong Check the earth connection and clamp
for correct polarity
No welding current
Mains switch is ON and indicators are
lit up
Check interconnecting cable
Exchange the torchBreak in the current cable in the welding
torch
Interconnecting cable defective or not
connected up properly (not on TotalArc²
3000)
Welding torch / torch control lead defec-
tive
Exchange the torch
No shielding gas
All other functions are OK
Gas solenoid valve is defective Change the gas solenoid valve
Gas cylinder is empty
Gas pressure regulator is faulty
Gas hose is not mounted or is damaged
Welding torch is defective
Change the gas cylinder
Change the gas pressure regulator
Mount / change the gas hose
Change the welding torch

Fault Cause Remedy
Check mains supply lead, make sure
mains plug is plugged in
Machine does not function
Mains switch is ON, but indicators are
not lit up
Do not exceed duty cycleNo welding current
Mains switch is ON, overtemperature
indicator is lit up
Mains outlet socket or plug is faulty
Break in mains lead, mains plug not
plugged in
Mains fuse is faulty
Change faulty components
Change mains fuse
Fan in power source is defective
Machine is overloaded, duty c. has been
exceeded
Thermostatic cut-out system has been
tripped
Change the fan
Wait until machine automatically co-
mes back on after end of cooling phase
