Controls)
If unit is equipped with optional Sequence
Controls (see Section 4-13), 4T trigger
method is available.
4T torch trigger operation is as shown.
While in 4T mode, there is a feature avail-
able during the main weld sequence that al-
lows the operator to toggle between weld

the arc.
NOTE: When a remote switch is connected
to the welding power source, only trigger in-
put is functional. Amperage is controlled by
the welding power source.
Application:
Use 4T trigger method when the functions
of a remote current control are desired, but
only a remote on/off control is available.

put is functional. Amperage is controlled by
the welding power source.
Application:
Use 4T Momentary trigger method when
the functions of a remote current control are
desired, but only a remote on/off control is
available.
