C. 4T, 4Tm And 4TL Specific Trigger Method
4T and 4Tm Application:
Use 4T and 4Tm (modified) trigger
methods when the functions of a remote
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 connected
to the welding power source, use
the remote 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 operator 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 remote switch to control the
weld cycle. Amperage is controlled
by the welding power source.
