TIG WELDING TROUBLESHOOTING

PROBLEM

CAUSE

CORRECTION

Poor

Penetration

(Aluminum)

Low Amperage

Amperage setting is too low for material/thickness. Increase as needed and

reference chart on Welder.

Incorrect AC Balance

Decrease AC Balance to increase penetration and decrease cleaning effect.

Poor

Penetration

(Steel)

Low Amperage

Amperage setting is too low for material/thickness. Increase as needed and

reference chart on Welder.

Tungsten

Contaminated

Contact of Tungsten with Base Metal

Keep tungsten 1/8” to 1/4” from the base metal. If tungsten comes in contact

break off end and resharpen immediately.

Poor Weld

Appearance

Incorrect Positioning

The angle between the filler metal and the torch must be less than 90° otherwise

the filler metal will prematurely melt and glob off causing poor weld appearance.

Crater in the

End of the Weld

Bead

Insufficient Shielding Effect

Keep the torch on the base metal while the post flow shielding gas flows to

protect and cool the metal and tungsten.

Not Enough Filler Material

Reduce current with Pedal and add more filler at end of weld. It may also be

beneficial to back step to ensure no crater will form.

Weld Bead is

Cracking

Too Much Heat in Material

Reduce heat and allow more time between passes.

Base Metal is Absorbing Too Much Heat

Preheat base metal (consult welding codes for requirements).

Incorrect Filler Wire

Use appropriate filler wire type and diameter for the joint being welded.

Material is

Warping

Insufficient Clamping

Clamp work piece tightly and weld while clamps are in place.

Insufficient Tack Welds

Add more tack welds until rigidity and stiffness is developed.

Too Much Heat in Material

To reduce heat, it is best to spread the welding out around the area. This can be

done by using stitch welding techniques, alternating sides, and/or taking your

time and allowing the pieces to cool between passes.
