INSTRUCTIONS for
TC-1A TORCH CONTROL
25-Ft., P/N 34718
This remote fingertip control is designed to be taped to
any Tig torch handle and it allows the operator complete
contactor control and variable control of the welding
current.The TC-1A is available with 25-foot cable lengths
and includes prewired current and contactor control
plugs. The control knob of this torch handle potentiometer/switch is designed for right-or left-handed accessibility. By simply rotating the knob clockwise (off of zero)
the integral switch will energize the contactor, and
further regulation (clockwise) will increase the output
current up to the limit preset on the power source's main
control.
To use the remote torch control, proceed as follows:
F-15-171
November, 1997
1. Place the control in the most comfortable position that
allows complete torch and control manipulation, and
tape the control to the torch handle as illustrated.
Stretch the tape over the molding corners as needed.
CAUTION: Do NOT use metal clamps. They can pro-
duce high frequency shocks.
2. Insert the proper torch control cable plugs in the
appropriate remote current and contactor receptacle
on the power sources.
3. Set the power source's Remote/Panel toggle
swtich(es) to remote current and contactor receptacle on the power sources.
CAUTION: Make sure the switch/pot. of the Torch
Control is in its extreme counterclockwise
(zero) position prior to and after each welding operation.
In this position, the welding contactor is
deenergized and the torch electrode is electrically "cold" - thus eliminating the possibility of accidental shock to the operator.
