Front Panel Operation

Quick Start

Your new single phase inverter multi-function welder offers THREE WELDING FUNCTIONS in the same
power source. These functions can be selected with knob (6) on the front panel of the unit:
Fluxcore Wire Welding, "FCAW" and MIG Welding, "GMAW"
This welder offers the choice to weld in manual or synergic mode.
1. Manual Mode: The operator is required to set both the wire speed (Left Knob - 8- ) and the
welding voltage (Right Knob - 7 -). A setting chart can be found on page (28) of this manual.
2. Synergic Mode: As in manual function, the operator is required to set both the wire speed
(Left Knob -8-) and the welding voltage (Right Knob -7-) referring to the setting chart on
page (24). Once both parameters are set, the synergic function allows the operator to move
to different thickness of material to be welded simply adjusting the Left Knob (8). The correct
voltage will be automatically set by the machine's software.
Stick Welding, "SMAW"
Both rutile and basic electrodes can be welded. Welding current is adjusted using the Left Knob (8).
TIG Welding, "GTAW"
In the TIG position, a TIG torch with a trigger control and a gas valve in the handle is required.
The gas valve must be opened manually before welding and closed manually when welding is
completed. The arc is activated using the torch trigger. Using the Left Knob (-8-) welding current
can adjusted.
