2. No welding power
Mains switch turned on
Welding cable connection
interrupted.
Bad contact or no
contact
Check connections
Connect work piece

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 amount
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. Work piece sticks to welding
table
Bad contact to welding table
Use clamp or pliers
14.
