Mains switch is ON, overtemperature
indicator is lit up
No welding current
Mains switch is ON and indicators are
lit up

torch
Control plug is not plugged in
Welding torch / torch control lead defec-
tive
Interconnecting cable defective or not
connected up properly (not on TotalArc²
3000)
Gas cylinder is empty
Gas pressure regulator is faulty
Gas hose is not mounted or is damaged
Welding torch is defective

Not enough shielding gas, or none at all
Welding torch is leaking
Wrong contact tube, or contact tube is
worn out
Wrong wire alloy and/or wrong wire dia-
meter
Shielding gas is not suitable for this wire
alloy
Braking force is set too high
Contact tube is too narrow
Wirefeed inner liner in the welding torch
is defective
Wirefeed rollers are unsuitable for the
wire being used
Wirefeed rollers have wrong contact pres-
sure

Remedy
Check mains supply lead, make sure
mains plug is plugged in
Change mains fuse
Change faulty components
Do not exceed duty cycle
Wait until machine automatically co-
mes back on after end of cooling phase
Change the fan
Check the earth connection and clamp
for correct polarity
Exchange the torch
Plug in the control plug
Exchange the torch
Check interconnecting cable
Change the gas cylinder
Change the gas pressure regulator
Mount / change the gas hose
Change the welding torch
Change the gas solenoid valve
Check settings
Ensure good contact to workpiece
Check pressure regulator, gas hose,
gas solenoid valve, torch gas connec-
tion etc.
Change the torch
Change the contact tube
Check the wire spool
Check the weldability of the base metal
Use the correct shielding gas
Loosen the brake
Use a suitable contact tube
Check the wire inner liner for kinks, dirt
etc.
Use suitable wirefeed rollers
Optimise the contact pressure
