OUTPUT PROBLEMS

The wire feeder does not feed wire

1. Verify the power source is turned

 

and the drive rolls do not spin.

 

on.

 

 

2.

Verify the circuit breaker for the

 

 

 

wire feeder on the power source

 

 

 

has not tripped.

 

 

3.

Check that the gun trigger is

 

 

 

operating properly.

 

 

4.

If the motor thermal LED is illumi-

 

 

 

nated, wait approximately 1

 

 

 

minute before welding again.

 

 

 

Inspect the gun for feeding prob-

 

 

 

lems.

 

 

5.

Verify power is being supplied to

 

 

 

the wire feeder.

 

 

 

 

The wire feeds erratically, or the

1. Verify the correct drive rolls and

 

Motor Thermal LED lights.

 

inner wire guide are installed in

 

 

 

the wire drive.

 

 

2.

Check for sharp bends in the gun

 

 

 

liner.

 

 

3.

Examine the contact tip for wear

 

 

 

and proper size. Replace as nec-

 

 

 

essary.

 

 

4.

Check the gun liner. The welding

 

 

 

electrode should slide easily

 

 

 

through the gun.

 

 

5.

Verify the proper gun liner is

 

 

 

installed.

 

 

6.

Adjust the pressure arm.

 

 

7.

On bench models, make sure the

 

 

 

brake tension is not too tight.

 

 

8.

If using a wire conduit, verify the

 

 

 

wire slides easily through the

 

 

 

conduit.

 

 

 

 

The wire continues to feed when the

1. Check if the 2 step/Trigger

 

trigger is released.

 

Interlock switch is in the TRIG-

 

 

 

GER INTERLOCK position.

 

 

2.

Verify operation of the gun trig-

 

 

 

ger.

 

 

 

 

No shielding gas

1. Verify the gas supply is turned on

 

 

 

and not empty.

 

 

2.

Check the gas hose for cuts.

 

 

 

Make sure it is not crushed.

 

 

3.

Verify the shielding gas hose is

 

 

 

connected to the gun bushing or

 

 

 

welding gun.
