TROUBLESHOOTING GUIDE
FAULT
REASON
REMEDY
Excessive
Electrode Consumption
Improper size/or geometry of electrode for current
required
Use larger electrode
Excessive heating in holder
Check for proper contact
Contaminated electrode
Replace electrode
Contaminated Electrode
Base metal is dirty or greasy
For surface cleanliness use appropriate chemical cleaners alcohol, wire
brush or abrasive
Contaminant elements that our gas may exist
within the base material itself
If possible, improve base material. Modify welding parameters to
accommodate out gassing effect
Check for electrode contamination
Remove contaminated portion of electrode, regrind electrode
Electrode
Dimensions
Be sure electrode dimensions are appropriate for
application
Electrode tip dimensions vary according to the welding application—refer
to the guide
Tab 1
Cable Layout
In so far as possible, try to layout cables from power
supply to welding torch as straight as possible
Occasionally, cables are coiled like a garden hose. The coil becomes a
giant inductor causing resistance that reduces starting energy. Inductance
effects can also be caused by having welding power cables very close to
grounded steel plates.
Grounding Problems
Make sure clamps and clamp inserts are clean of
oxidation. Make sure ground clamp is not worn.
Oxidation and/ or worn equipment can cause poor ground between part
and clam/ inserts which may hinder arc starting, wander and other
inconsistencies.
Extension Cables
Ensure that any extension cables are of adequate
capacity
Low quality/ capacity cables will result in voltage drops and hinder starting
Overheat Lights Come On Overheating of unit
Allow 3—5 minutes of “cool down” time. If condition is not resettable, take
welder to repair agent for service.
Difficulty in Arc Starting
Damaged Electrodes
Check condition of electrodes
Check the power supply
Low voltage problem
Check the AMP settings
Arc Does Not Transfer
Loose, missing cable connections
Check earth connection for loose or poor ground
Power supply not recognising start signal
Check all connections
