(SYMPTOMS)

 

 

CAUSE

 

 

 

 

 

 

FEEDING PROBLEMS

 

 

 

 

 

 

 

 

The wire feed stops while welding.

 

 

1.

Check the wire feed drive rolls

 

 

 

 

 

 

When trigger is released and

 

 

 

and motor for smooth operation.

 

 

pulled again the wire feed starts.

 

 

2.

Check for restrictions in the wire

 

 

 

 

 

 

feed path. Check the gun and

 

 

 

 

 

 

cable for restrictions.

 

 

 

 

 

3.

Make sure gun liner and tip are

 

 

 

 

 

 

correct for wire size being used.

 

 

 

 

 

4.

Make sure drive rolls and guide plates

 

 

 

 

 

 

are clean and are the correct size.

 

 

 

 

 

5. Check spindle for ease of rotation.

 

 

 

 

 

 

 

 

 

No control of wire feed speed.

 

 

1.

The wire feed speed control may

 

 

Other machine functions are nor-

 

 

 

be dirty. Rotate several times

 

 

mal.

 

 

 

and check if problem is resolved.

 

 

 

 

 

 

GAS FLOW PROBLEMS

 

 

Gas does not flow when gun trigger

 

 

1.

Make sure gas supply is con-

 

 

is pulled.

 

 

 

nected properly and turned “on”.

 

 

 

 

 

2.

If the gas solenoid does actuate

 

 

 

 

 

 

(click) when the gun trigger is

 

 

 

 

 

 

pulled there may be a restriction

 

 

 

 

 

 

in the gas supply line.

 

 

 

 

 

3.

The gun cable assembly may be

 

 

 

 

 

 

faulty. Check or replace.

 

 

 

 

 

4.

If gas solenoid does not operate

 

 

 

 

 

 

when gun trigger is pulled the

 

 

 

 

 

 

problem is within the POWER

 

 

 

 

 

 

MIG 215.

 

 

 

 

 

5.

Make sure the gun is pushed all

 

 

 

 

 

 

the way into gun mount and is

 

 

 

 

 

 

properly seated.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

RECOMMENDED COURSE OF ACTION

If all recommended possible areas of misadjustment have been checked and the problem persists,

Contact your local Lincoln Authorized Field Service Facility.

CAUTION

If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your

LOCAL AUTHORIZED LINCOLN ELECTRIC FIELD SERVICE FACILITY for assistance before you proceed.
