TROUBLESHOOTING GUIDE

WARNING

ELECTRIC

SHOCK can kill

•Have an electrician install and service this equipment.

•Turn the input power off at the fuse box before working on equipment.

•Do not touch electrically hot parts.

Problem

Possible Cause

What To Do

Rough wire feeding or wire not feeding but drive rolls turning.

Gun cable kinked and/or twisted. Wire jammed in gun and cable.

Inspect gun cable and replace if necessary.

Remove wire from gun and cable - feed in new wire. Note any obstructions in gun and cable. Replace gun and cable if necessary.

 

Incorrectly fitted drive roll.

See Wire Drive Roll Section in this manual for proper

 

 

installation of drive roll.

 

Drive roll loose.

Remove, clean, install and tighten.

 

Gun cable dirty.

Clean cable or replace liner.

 

Worn drive roll.

Replace.

 

Electrode rusty and/or dirty.

Replace.

 

Worn nozzle or cable liner.

Replace.

 

Partially flashed or melted contact tip.

Replace contact tip.

 

Incorrect idle roll pressure.

Set idle roll pressure.

 

 

 

Variable or “hunting” arc.

Wrong size, worn and/or melted contact tip.

Replace tip - remove any spatter on end of tip.

 

Worn work cable or poor work connection.

Inspect - repair or replace as necessary.

 

Loose electrode connections.

Be sure electrode lead is tight, gun cable tight in wire

 

 

feeder contact block, gun nozzle and gun tip tight. All

 

 

work lead connections must be tight.

 

Wrong polarity.

Check connection at output studs for polarity required
