Additional Features

A multi-coloredprocess selector control allows quick and easy process changes without having to use multiple switches.

Heavy-Duty Design — The Vault design provides enhanced arc characteristics that include more dig in the Stick mode with smoother and lower amperage in the TIG mode. Along with the superior welding performance, the Vault provides the ultimate reliability in the harshest of environments.

A hermetically-sealed vault protects Miller
