SETUP GUIDELINES FOR TIG WELDING

WITH AN AMPTROL

Both the Hand and Foot AMPTROLS work in a similar manner. They are meant to be used for remote current control for TIG welding using the machineʼs 2-Steptrigger mode (See Item 12).

The Amptrol is capable of controlling the output of the Precision TIG over the range between the level preset by the Minimum Output control when the Amptrol is at its inactivated state, and the level preset by the Maximum Output control when the Amptrol is at fully- activated state.

It is important to note that even with the Precision TIGʼs new MicroStartTM Technology, some tungstens may be difficult to start at the low (2 amps) minimum rating of the machine. Rather than guessing where to depress the Amptrol to start the arc reliably, the Minimum Output control allows presetting the exact level, so reliable starts, as well as minimum crater-fill levels, can be consistently obtained at the minimum Amptrol (inac- tivated ) state. FIGURE B.6 shows Precision TIG setup for TIG welding with an Amptrol.
