6-2. TROUBLESHOOTING CHECK LIST
ERROR CAUSE
SOLUTION
1. No welding power
Mains switch turned on Operation
signal does not light up
Interrupted cable
Check cable and Mains
2. No welding power
Mains switch turned on
Operation signal green
Welding cable connection
interrupted.
Bad mass or no
mass
Check connections
Connect work piece
Fasten contact clamp directly to
work piece.
3. No welding power
Mains switch turned on
Operation signal constant (red)
Error by fault current
Press reset button or switch device
off and on
If malfunction continues, send
device to be serviced
4. Poor ignition
poor contact with mass
dirty electrode
Tip of electrode burnt off
Connect work piece
Grind electrode
Grind electrode
5. Mains Fuse and/or safety cut-out
has tripped
Mains fuse too weak, Incorrect
safety cut out
Mains fuse is tripped under no-
load conditions
Insert correct fuse
Send device to service
6. Poor welding characteristics
wrong protective gas
no protective gas
Use inert protective gas (ARGON
4.6)
7.Oxidation and rust formation
Heavy gas pressure sufficient
Reduce flow through amount – 3-4
l/min.are
8. Strong oxidation
of welding spots
wrong protective gas
no protective gas
Use inert protective gas (ARGON
4.6)
9. Tungsten contamination
in basic material
Electrode with too high pressure
onto work piece
Touch work piece with very slight
pressure so that it manages to
ignite
10. Tungsten Electrode
sticks to work piece
Electrode with too high pressure
onto work piece
Touch work piece with very slight
pressure so that it manages to
ignite
11. Tungsten Electrode
fuses immediately
Grinding too sharp
Grind in recommended angle (25°)
12. Static discharge onto the
device surface
Special situation at your location
Use special foot mat for the work
area
13. Workpiece sticks to welding
table
Bad contact to welding table
Use clamp or pliers
ATTENTION: The device should be opened by trained personnel only!
