Access to sub-menu functions is easily performed. Press and hold Left-hand side Button for 2
seconds will access the following functions, then the MIG-LED flashes right now.
• Wire Run-In speed: Indicated as “RIN” within Left-hand side LED display Value is
adjusted by Right-hand side Encoder and is measured in either as IPM or MPM
depending on user choice. The value is displayed within Right-hand side LED Display
and is adjusted and as a percentage of chosen WFS
• Pre-Gas Time: Indicated as “PRG” within Left-hand side LED Display with a value
shown in Right-hand side LED Display. Value is adjusted by Right-hand side Encoder
and is measured in seconds.
• Post-Gas Time: Indicated as “POG” within Left-hand side LED Display with a value
shown in Right-hand side LED Display. Value is adjusted by Right-hand side Encoder
and is measured in seconds.
• Wire Burn-Back Time: Indicated as “Bb” within Left-hand side LED Display with a
value shown in Right-hand side LED Display. Value is adjusted by Right-hand side
Encoder and is measured in seconds.
Existing the sub-menu is easily completed. The operator can choose between pressing and
holding Left-hand side Button for 2 seconds or alternatively, by pressing the torch trigger.
b) Inductance functions
Short pressing Right-hand side Button will access the Inductance functions, Inductance is used
during the MIG/MAG welding process. Inductance setting is indicated as “IND” within Left-hand
side LED Display with a value shown in Right-hand side LED Display. The inductance value is
adjusted by Right-hand side Encoder .This is factory set to “5” adjustment is 1 to 9 (range is 1 to 9)
c) MIG Welding Process (2T/4T)
i. Under this menu, the 2T/4T LED flashes. Left-hand side LED Display shows "TRG",
Rotation Right-hand side Encoder switch 2T&4T mode.
ii. Trigger Hold: Two modes of trigger are available for the operator to choose from. The
default mode is 2T, effectively an “2T& 4T” for Arc start /stop.
iii. Additionally the operator can select 4T mode. This mode enable the operator to release
the trigger and maintain the arc. By depressing the trigger once more and releasing,
the arc will initiate end of weld sequence (Wire Burnback time, followed by Post Gas-
Flow time if values have been set). When 4T is active 2T/4T LED remains illuminated.
11. Arc control (inductance)
The arc control operates in MIG mode only and is used to adjust the intensity of the welding
arc. Lower arc control settings make the arc softer with less weld spatter. Higher arc control
settings give a stronger driving arc which can increase weld penetration. Soft means
maximum inductance while Hard means minimum inductance.
12. Trigger mode control
The trigger mode control is used to switch the functionality of the of the torch trigger between
2T (normal) and 4T (latch mode).
2T (Normal mode)
In this mode, the torch trigger must remain depressed for the welding output to be active.
Press and hold the torch trigger to activate the power source (weld). Release the torch trigger
switch to cease welding.
