TROUBLESHOOTING

SYMPTOM

POSSIBLE CAUSE

CORRECTIVE ACTION

Unit Does Not Power Up

Unit Is Not Plugged In

Plug In Unit

Input Power Circuit Breaker Not On

Reset Input Power Circuit Breaker

The Main Power Switch Is Not Working

Replace Main Power Switch

Can Not Create An Arc

Work Piece is Painted Or Rusty

Remove All Paint And Rust

Ground Clamp Is Connected Where There

Is Paint Or Rust

Remove All Paint And Rust So Ground

Clamp Is Connected To Bare Metal

Ground

Clamp Is Not Electrically

Connected To The Work Piece

Make Certain The Ground Clamp Is

Connected To The Work Piece

Amperage Too Low for Electrode

Consult the electrode packaging for

correct amperage settings.

Overload Indicator Is On

The internal temperature is too high.

Leave power on and let the fan cool the

unit. Output will continue when the unit has

cooled.

Electrode Holder or ground cable getting

hot. Output Connections Getting Hot.

Weld Cable Connections Loose

Check to make certain weld cables are

tight.

Weld Cable Connections have corroded.

Clean weld connections and reinstall.

Poor Welding Performance, excessive

spatter

Damp Electrode

Use fresh and dry electrodes.

Electrode Sticks

The electrode is kept in contact with the work

piece for too long while striking an arc.

This will take practice. Keep trying.

Welding Bead Is Too Thin

The welding travel speed is too fast

Reduce the welding travel speed. Maybe

incorporate a slight weave over the joint.

Welding Bead Is Too Thick

The welding travel speed is to slow

Increase the welding travel speed.
