When MIG mode is selected
MIG/MAG welding process left side first LED is illuminated
Left-hand side LED display Indicates set welding voltage (V). Rotating Left-hand side encoder
CW (Clockwise) will increase welding voltage value. Rotating Left-hand encoder CCW
(Counter-Clockwise) will reduce Welding voltage value. (Min and Maximum range see table)
Right-hand side LED display Indicates set welding Wire Feed Speed (WFS) value. Rotating
Right-hand side Encoder CW (Clockwise) will increase welding WFS value. Rotating Right-
hand side Encoder CCW (Counter-Clockwise) will reduce WFS value. (Min and Maximum
range see table)
Pressing and holding both Push Left-hand side Button and Push Left-hand side Button
simultaneously for 2 seconds, the unit selection menu is activated. The MIG-LED flashes right
now. Rotate the Left-hand side Encoder to switch the preset unit and the working unit
adjustment. At preset unit adjustment, Left-hand side LED displays "UNT", Rotate Right-hand
side Encoder Switch Metric and Imperial, namely IPM and MPM (Meters Per Minute); during
working unit adjustment, Left-hand side LED displays "DIS", Rotate Right-hand side Encoder
Switch current and wire delivery speed, namely WFS and AMP. Press Left-hand side Button
short or trigger the welding gun switch to exit the unit selection menu

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.
