3.07 LIFT TIG (GTAW) Setup

Secure the gas cylinder in an
upright position by chaining it
to a stationary support to prevent
falling or tipping.
LIFT TIG (GTAW) Sequence of Operation
Before any welding is to begin, be sure to wear all
appropriate and recommended safety equipment.
1. Switch the ON/OFF Switch (located on the rear panel)
to OFF.
2. Connect the ground clamp cable to positive output
terminal, and the TIG torch cable to the negative
