INSTRUCTIONS for
TC-2B TORCH CONTROL
F-15-123-A
May, 2003
30-FT., P/N 33839
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-2B is available with 30-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 limit preset on the power source’s
main control.
To use the remote torch control, proceed as follows:
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.
1. Place the control in the most comfortable position
that allows complete torch and control manipulation,
and tape the control to the torch handle. Stretch the
tape over the molding corners as needed.
2. Insert the torch control cable plug in the remote
current and contactor receptacle on the power
source.
3. Set the power source Remote/Panel toggle
switch(es) to the Remote position.
4. Set the power source main “current control” to the
maximum current to be used.
5. Rotate the torch control knob clockwise (from zero)
to energize the contactor, and continue rotation until
the desired welding current is achieved.
