6. Wirespeed Control (MIG) Amps Control (Stick & TIG)
In MIG (GMAW/FCAW) modes , the Wirespeed Control knob adjusts the speed of the wire feed motor (which in
turn adjusts the output current by varying the amount of MIG wire delivered to the welding arc). The optimum
wire speed required will dependent on the type of welding application. The setup guide on the inside of the
wire feed compartment door provides a brief summary of the required output settings for a basic range of
MIG welding applications.
The amps control knob adjusts the amount of welding current delivered by the power source. In Stick (MMAW)
and TIG (GTAW) modes, the Amps control knob directly adjusts the power inverter to deliver the desired level
of output current.
7. Voltage Control
In MIG (GMAW/FCAW) mode, the voltage control knob is used to adjust the output voltage of the unit. The
welding voltage is increased by turning the knob clockwise or decreased by turning the knob anti-clockwise.
The optimum voltage level required will be dependent on the type of welding application. The setup chart on
the inside of the wire feed compartment door provides a brief summary of the required output settings for a
basic range of MIG welding applications.
8. Digital Amps Meter (Left Digital Display)
MIG Mode
This digital meter is used to display the pre-set (preview) Wirefeed Speed in Metres Per Minute (MPM)
in MIG mode and actual welding amperage of the power source when welding. At times of non-welding,
the digital meter will display a pre-set (preview) value of Wirefeed Speed (MPM). This value can be
adjusted by varying the Wirespeed Control Knob (6).
STICK and LIFT TIG Modes
The digital meter is used to display the pre-set (preview) amperage in STICK / LIFT TIG modes and
actual welding amperage of the power source when welding. At times of non-welding, the amperage
meter will display a pre-set (preview) amperage value in both STICK and LIFT TIG modes. This value
can be adjusted by varying the Amps Control Knob (6).
When welding, this digital meter will display actual welding amperage in all modes.
At the completion of welding, the digital meter will hold the last recorded amperage value for a period
of approximately 10 seconds in all modes. The amperage meter will hold the value until; (1) any of
the front panel controls are adjusted in which case the unit will revert to preview mode, (2) welding is
recommenced, in which case actual welding amperage will be displayed, or (3) a period of 10 seconds
elapses following the completion of welding in which case the unit will return to preview mode.
NOTE
The preview functionality provided on this power source is intended to act as a guide only. Some dierences may be
observed between preview values and actual welding values due to factors including the mode of welding, dierences
in consumables/gas mixtures, individual welding techniques and the transfer mode of the welding arc (ie dip versus
spray transfer). Where exact settings are required (in the case of procedural work), it is recommended that alternate
measurement methods be utilised to ensure output values are accurate.
