TROUBLESHOOTING AND FAULT FINDING
Notes: The following operations must be performed by qualified electricians with valid
certifications. Before maintenance,please contact with us for professional suggestion.
fault symptom and solutions:
Faults Resolvable Methods
Fan does not Work and
numerical screen is not
indicating, there is no welding
output
1. Make sure power switch is closed
2. Make sure electrify wire net of output cable can supply power
3. Some of heat-variable resistors (four) of power panel is damaged,
when it happen ,general DC24V relay is open or connectors is poor
contact
4. Power panel (bottom board ) is damaged, DC537V or DC587V
voltage can be output
5. Auxiliary power of control panel is in fault
6. The transformer is damaged
Fan works, abnormal indicator
is not lit ,there is no sound of
HF arc-striking, wiping arc
welding can not strike arc
1. Check if all kinds of cables of inter-machine are poor contact
2. There is some fault in control panel, find out reason and connect
with seller
3. Control cable of torch is broken
Abnormal Indicator is not lit
,sound of HF arc-striking can
be heard, there is no welding
output
1. Torch cable is broken
2. Grounding cable is broken or not connected to welding piece
3. Positive electrode terminal or torch electrify terminal is loosed from
inter-machine
Abnormal indicator is not
lit ,there is no sound of HF arc-
striking ,wipe
welding can strike arc.
1. Primary cable of arc-striking transformer is not connected to arc-
striking panel reliably, tighten it again
2. Arc-striking tip is oxidized or too far, give a good polish to it or
change it is about 1 mm between arc-striking tip
3. Switch (sticking/argon-arc welding) is damaged, replace it
4. Some of HF arc-striking circuit components is damage, find out
and replace it
