There is no other operation style similar to
a foot pedal for MIG. The "T" refers to the
number of "travels" of the remote switch
required to operate the programming of
the sequencer. 2T is essentially a "press
and hold" operation and all programming is
cycled automatically. Releasing the switch
begins the final stage of programming. 4T
operates differently in the fact that each
touch activates a different stage of the pro-
gramming, allowing for greater control. In
4T mode, while welding at full selected val-
ue (MIG: Volts, TIG: Amps), no finger con-
tact with the switch is required. Following
the graphic lines below, you can visually
trace the activity and function of each part
of the welding cycle. In either 2T or 4T op-
eration the programming can be reset to
"upslope" before reaching the end amp
stage by pressing the switch once more.
See the graphics below for further explana-
tion. The up and down arrows indicate the
switch travel direction.
