Crafting Quality: TIG Troubleshooting

Operating of reverse polarity ->	Change the polarity or use a larger electrode
Excessive heat inside of the torch -> ​	Replace the collet or try wedge or reverse collet
Electrode is oxidizing during cooling  ->	Increase the gas post flow to 1 sec/10 amps

Poor scratch starting technique -> ​	Use a copper strike plate or a high frequency arc starter
Accidental contact of electrode with the puddle or filler rod -> ​	Maintain proper arc length and a distance between electrode and filler metal
Inadequate shielding or excessive draft -> ​	Increase the gas flow, use a gas lens or shield the arc from wind

Current is too low for electrode size -> ​	Use a smaller sized electrode or increase the current
Base metal is dirty, oil, or oxidized -> ​	Prior to welding, clean the base metal with chemical cleaners, a wire brush, or abrasives
An indication of contaminated shielding gas is dark stains on the weld bead or the electrode -> ​	The most common cause of contaminated gas is moisture or aspirated air that has gotten into the gas stream

Hot cracking   -> ​	Preheat your material or increase weld bead size
Post weld cold cracking -> ​	This is due to excessive joint restraint, hydrogen embrittlement or rapid cooling- before welding, make sure your gas is not contaminated, increase the weld bead size or change the joint design
Centerline cracks in a single pass weld -> ​	Increase the bead size, decrease the root opening, or preheat

Operating of reverse polarity -> ​	Change the polarity or use a larger electrode
Excessive heat inside of the torch  -> ​	Replace the collet or try wedge or reverse collet
Electrode is oxidizing during cooling -> ​	Increase the gas post flow to 1 sec/10 amps

Cup shattering or breaking -> ​	Change cup size or type or the tungsten position
Ordinary collet is split or it twists or jams -> ​	Switch to a wedge style
Gas hose is ballooning, bursting, or blowing off ->	Check your flowmeter to ensure it is meant for TIG as the psi needs differ from MIG flowmeters

The best way to learn and improve is to try and adjust. Use this troubleshooting guide to help you find the root causes of common issues you may run into while TIG welding!
