D. 4T Specific Trigger Method
1 4T (Specific Trigger Operation)
2 Encoder Control
To select 4T, turn Encoder control.
Torch trigger operation is as shown.
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.
Application:
Use 4T trigger method when the functions of a remote current
control are desired, but only a remote on/off control is available.

2 Encoder Control
To select Mini Logic, turn Encoder control.
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-
able. Final slope will always slope to minimum amperage
and end the cycle.
When a remote switch is connected to the welding pow-
er 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.
