Trouble RemedyProbable Cause
Shutdown at arc initiation using robot
controller
No arc detected Check for arc detect signal coming from interface
Robot times out before arc detected Add more time for robot arc detect input, verify weld
parameters, and check weld circuit
Robot command scaling not set properly Set proper robot command scaling
Time between welds too short Adjust welding cycle time
Welding sequence problems Power source should energize and welding wire
should start feeding at the same time
No wire feed speed command Set wire feed speed
No voltage command Set voltage
Shutdown at arc initiation due to weld cir-
cuit condition
Poor part fit up at weld joint, wire not making contact
with workpiece
Check part consistency for fitup and/or position gun
so wire always contacts part
Poor connection in weld circuit Check welding gun, torch, contact tip adapter, con-
tact tip, weld cable connections and any rotary or
brush type connection
Improper gas flow causing start and timeout issues Check for correct shielding gas and flow adjust-
ment
