Problem

Press gun trigger, wire dose not feed

and gas does not flow

Press the gun trigger, OCV is on,

no wire feeding

Rough wire feeding or no wire feeding

Problem Cause

• Remote control cable connector are

not connected securely to the

receptacle

• Gun trigger switch is damaged

• Loose remote control cable

connection(include the motor control

circuit and other)

• Wire or rust or dirt jammed in gun

and cable

• Incorrect size or installation of drive

roll and guide tubes

• Gun cable kinked and /or twisted

• Drive roll loose

•Worn drive roll

•Gun cable dirty

• Worn nozzle or cable liner

Partially flashed or melted contact tip

• Wire reel brake tension set

too high or low

What to do

Check and make certain that the

connection is good

Replace the gun trigger switch

Check and make sure that remote

control cable connectors are in good

contact.

Check and clean the line of gun

Replace the drive roll

Make line straight

Tight the drive roll

Replace the drive roll

Clean the gun cable

Replace the worn nozzle or cable liner

Replace the contact tip

Adjust the satisfactory tension for reel
