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 machine's 2-Step
trigger 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
's new MicroStart
TIG
®
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 (inactivated ) state. FIGURE b.6 shows
