4T And 4Tm Application:
Use 4T or 4Tm (modified) trigger
method when the functions of a re-
mote current control are desired,
but only a remote on/off control is
available.
4T* allows the operator to toggle
between weld current and final
current.
.
When a remote switch is con-
nected to the welding power
source, use the remote switch
to control the weld cycle. Am-
perage is controlled by the
welding power source.
4TL Application:
The ability to change current levels
without either initial slope or final
slope, gives the operator the oppor-
tunity 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 con-
nected to the welding power
source, use the remote switch
to control the weld cycle. Am-
perage is controlled by the
welding power source.
