7.3 TIG WELDING FOOT PEDAL
CURRENT CONTROL – FIG.7
The foot pedal
(10)
allows the welding current to be
adjusted remotely from the main welding unit.
To connect the foot pedal:
− Plug both the 6 pin
(3.1)
and 2 pin
(2.1)
connector
plugs of the foot pedal into the corresponding ports
(3)
/
(2)
located on the machine (the 2 pin plug
connector of the TIG torch
(7.1)
becomes redundant
and can be left hanging loose).
Operation:
− Set the dial
(10.1)
located on the side of the pedal to
the desired current output.
− Depress the foot pedal to activate. The resulting
pressure placed on the pedal controls the level of
current incrementally until the maximum level, set by
the dial is reached.

The correct selection of electrode size and type will vary
for each application dependent upon material thickness,
material type, amperage and equipment, however as a
