1: No wire feed

Possible Reason

Suggested Remedy

Wrong mode selected

Check that the TIG/ARC/MIG selector switch set to MIG position

Wrong torch selector switch

Check that the STANDARD/SPOOLGUN selector switch is set to STANDARD position

for MIG welding and SPOOLGUN when using the Spoolgun

2: Inconsistent / interrupted wire feed

Possible Reason

Suggested Remedy

Adjusting wrong dial

Be sure to adjust the WIRE FEED and VOLTAGE dials for MIG welding.

The AMPERAGE dial is for STICK and TIG welding mode

Wrong polarity selected

Select the correct polarity for the wire being used - see machine setup guide

Incorrect wire speed setting

Adjust the wire feed speed

Voltage setting incorrect

Adjust the voltage setting

Mig torch lead too long

Small diameter wires and soft wires like aluminium don’t feed well through long torch

leads - replace the torch with a lesser length torch

Mig torch lead kinked or too sharp

angle being held

Remove the kink, reduce the angle or bend

Contact tip worn, wrong size, wrong

type

Replace the tip with correct size and type

Liner worn or clogged (the most

common causes of bad feeding)

Try to clear the liner by blowing out with compressed air as a temporary cure,

it is recommended to replace the liner

Wrong size liner

Install the correct size liner

Blocked or worn inlet guide tube

Clear or replace the inlet guide tube

Wire misaligned in drive roller groove Locate the wire into the groove of the drive roller
Incorrect drive roller size

Fit the correct size drive roller eg; .030in wire requires .030in drive roller

Wrong type of drive roller selected

Fit the correct type roller (e.g. knurled rollers needed for flux cored wires)

Worn drive rollers

Replace the drive rollers

Drive roller pressure too high

Can flatten the wire electrode causing it to lodge in the contact tip - reduce the drive

roller pressure

Too much tension on wire spool hub Reduce the spool hub brake tension
Wire crossed over on the spool or

tangled

Remove the spool untangle the wire or replace the wire

Contaminated mig wire

Use clean dry rust free wire. Do not lubricate the wire with oil, grease etc

The following chart addresses some of the common WIRE FEED problems during MIG welding. In all cases of equipment

malfunction, the manufacturer’s recommendations should be strictly adhered to and followed.

MIG WIRE FEED TROUBLE SHOOTING

6: Lack of Penetration − shallow fusion between weld metal and base metal

Poor in incorrect joint preparation

Material too thick. Joint preparation and design needs to allow access to bottom of

groove while maintaining proper welding wire extension and arc characteristics

Keep the arc at the leading edge of the weld pool and maintain the gun angle at

5 & 15° keeping the stick out between 1/8-1/4in

Not enough heat input

Select a higher voltage range and /or adjust the wire speed to suit

Reduce travel speed

Contaminated base metal

Remove materials like paint, grease, oil, and dirt, including mill scale from base metal.
