This manual was edited to give some indications on the operation of the welder and was thought to offer
information for its practical and safe use. Its purpose is not to teach welding techniques. All suggestions
are indicative and intended to be only guide lines.
To ensure that your welder is in good conditions, inspect it carefully when you remove it from its packing
having care to ascertain that the cabinet or the stocked accessories are not damaged.
Your welder is capable of daily activity metal fabrication and maintenance. Its simplicity and versatility and
its excellent welding characteristic are the product of the most up to date inverter technology. This welding
inverter offers the welder the ability to create precise arc characteristics and at the same time reduce con-
sumption of energy with respect to the welders based on a traditional transformer.
Respect the duty cycle of the welder making reference to the technical data label on the welder's back.
Duty cycle is given as percentage on a 10 minute time. During this period of time the unit can be used at
the rated duty cycle. Exceeding the rated duty cycle may cause overheating or welder damage.
Welder's basic specifications:
You may find the data table of your machine in the last page of this manual.
Welding Wire Selection:
This welder can work with Aluminum wire 0,8÷1,0 diameter, solid steel wire 0,6÷1,0 diameter and stainless
steel wire 0,8÷1,0 diameter (Gas Welding) and with flux core wires 0,9 diameter (No Gas Welding).
Feed Rolls:
groove 0,6-0,8mm for wires 0,6÷0,8mm
groove 1,0-1,2mm for wires 1,0mm
Knurled groove 0,9 for flux core wire 0,9mm
U-groove feed rolls for Aluminum, groove 0,8-1,0mm for wires 0,8-1,0mm
Gas Selection
According to the material to be welded and to the wire you are going to use, select the shielding gas. The

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:
MIG (GMAW and FCAW) Welding with Gas and without Gas
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 -).
2. Synergic Mode: the operator is required to simply set the thickness of the material to be welded (Left
Knob -8-). Once this parameter is set, the synergic function automatically adjusts the wire speed and
the welding voltage allowing the operator to balance this last value simply adjusting the Right Knob (7).
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 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 by contact. Using
the Left Knob (8) welding current can adjusted.
