TIG Welding with Inverters vs Transformers

TIG Welding with Inverters vs Transformers

Posted by Sean on Feb 13th 2017

A question we often get is "I have an inverter (or transformer) unit, which tungsten should I use?"

The update to our electrode selection chart below should answer that at a glance. The selection of a power source is determined primarily by the metal type and its thickness. Other considerations should be machine size and portability (inverters being smaller/lighter) and energy-efficiency (inverters draw less power). Send us an email if you have questions.
