**Arc can be extinguished at final slope rate at any time by pushing and holding trigger.
4T And 4Tm Application:
Use 4T or 4Tm (modified) trigger method
when the functions of a remote current con-
trol are desired, but only a remote on/off con-
trol is available.
4T* allows the operator to toggle between
weld current and final current.
�
When a remote switch is connected to
the welding power source, use the re-
mote switch to control the weld cycle.
Amperage is controlled by the welding
power source.
4TL Application:
The ability to change current levels without
either initial slope or final slope, gives the op-
erator the opportunity to adjust filler metal
without breaking the arc.
4TL (mini logic) allows the operator to toggle
between initial slope or main amps and initial
amps. Final Amperage is not available. Final
slope always slopes to minimum amperage
and ends the cycle.

When a remote switch is connected to
the welding power source, use the re-
mote switch to control the weld cycle.
Amperage is controlled by the welding
power source.
