8-12. Welding Troubleshooting
Trouble
Remedy
No weld output.
Check weld control settings.
Check weld connections.
Disconnect equipment from generator power receptacles during start-up.
Increase front panel and/or remote voltage/amperage control settings (see Sections 5-12 and 6-1).
Check and secure connections to Remote receptacle RC4 (see Sections 5-12).
Have Factory Authorized Service Agent check brushes, slip rings, and circuit boards PC1 and PC2.
Low weld output.
Check control settings.
Increase front panel and/or remote voltage/amperage control settings (see Sections 5-12 and 6-1).
Check and clean air cleaner as necessary (see Section 8-5).
Check engine speed, and adjust if necessary (see Section 8-8 or 8-10).
Have Factory Authorized Service Agent check brushes, slip rings, and circuit boards PC1 and PC2.
See engine manual.
High weld output.
Check control settings.
Check and adjust engine speed (see Section 8-10 or 8-8).
Check for obstructed movement of solenoid linkage (see Section 8-8 or 8-10).
Have Factory Authorized Service Agent check circuit boards PC1 and PC2.
Weld output cannot be adjusted.
Have Factory Authorized Service Agent check field current control board PC2.
Erratic weld output.
Check control settings.
Clean and tighten connections both inside and outside unit.
Check and secure lead connections to remote control.
Be sure connection to work piece is clean and tight.
Remove excessive coils from weld cables.
Use dry, properly stored electrodes.
Check and adjust engine speed (see Section 8-8 or 8-10).
Have Factory Authorized Service Agent check brushes, slip rings, and circuit boards PC1 and PC2.
Check shielding gas, ensure proper shielding gas coverage while welding.
No remote voltage/amperage control.
Check and tighten connections to Remote receptacle RC4 (see Section 5-12). Check and secure
lead connections to remote control.
No front panel voltage/amperage
control.
Disconnect remote control from Remote receptacle RC4 if not needed for weld process (see Section
5-12).
No 24 volt AC power output at Remote
receptacle RC4.
Reset supplementary protector CB4 (see Section 8-11).
No 115 volt AC power output at Re-
mote receptacle RC4.
Reset supplementary protector(s) CB1 and/or CB3 (see Section 7-1).
Lack of high frequency; difficulty in
establishing Gas Tungsten Arc Weld-
ing arc.
Use proper size tungsten for welding amperage.
Reduce leakage of high frequency from torch or work cable (check grounding, remove excessive
coils from weld cables, use shorter weld cables, etc.).
Check cables and torch for cracked or deteriorated insulation or bad connections. Repair or replace
necessary parts.
