1 4T (Specific Trigger Operation)
Select 4T according to Section 6-2C.
Torch trigger operation is as shown.
4T allows the operator to toggle between weld current and final
current.
NOTE: When a remote switch is connected to the welding pow-
er source, use the remote switch to control the weld cycle. Am-
perage 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.

1 Mini Logic Meter Display
Select Mini Logic according to Section 6-2C.
Torch trigger operation is as shown.
Mini logic allows the operator to toggle between initial slope
or main amps and initial amps. Final Amperage is not avail-
Mini Logic
able. Final slope will always slope to minimum amperage
and end the cycle.
NOTE: 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.
Application: This ability to change current levels without ei-
ther initial slope or final slope, gives the operator the opportu-
nity to adjust filler metal without breaking the arc.
