What polarity is recommended when gas tungsten arc welding (GTAW) also known as tungsten inert gas (TIG) welding?

ANSWERED BY PAT | SEPTEMBER 19, 2018

Negative polarity is recommended for GTAW (TIG welding) because this prevents the tungsten electrode from overheating.

As a Wesfarmers company, Coregas is the only Australian-owned gases company. We manufacture gases locally and distribute throughout Australia and New Zealand via a network of branches and third parties.
