TROUBLE SHOOTING
ERROR
CAUSE
SOLUTION
1
No welding power
Power main switch on.
Power connection interrupted
Check power connection and
main voltage
Display stays off
2
No welding power
Power main switch on.
Welding cable connection
interrupted
Check connectors
Bad or no grounding
Connect to work piece. Attach
contact clamps directly to the
work piece
3
No welding power
Interruption due to power error
Power main switch on.
Press the reset button or turn
device on and off
If still error, take device to be
serviced
Equipment to technical service
4
Hard to ignite
Bad grounding contact
Connect to work piece
Dirty electrode
Re-sharpen electrode
Burned down electrode tip
Re-sharpen electrode
5
Power fuse and/or automatic
safety blows
Not enough power protection
Install proper power protection
Wrong automat
Mains fuse releases in the no-
load operation
Send device to be serviced
6
Welding unsatisfactory
Wrong safety gas, no inert gas
Use inert gas (Argon 4.6)
7
Oxidation and soot development Gas pressure too high
Reduce flow to ca. 3 to 4 l/min
8
Heavy oxidation development on
the welding spot
Wrong safety gas, no inert gas
Use inert gas (Argon 4.6)
9
Tungsten in basic material
Too much electrode pressure on
the work piece
Lightly touch work piece so that it
barely ignites enough
10
Tungsten electrode adheres to
work piece
Too much electrode pressure on
the work piece
Lightly touch work piece so that it
barely ignites enough
11
Tungsten electrode melts off
Tip sharpened too much
Sharpen to the recommended
angle (ca. 15°)
12
Static discharge over the device
surface
