2.6 SAFETY INSTRUCTIONS
For your safety, before connecting the power source to the line, closely follow these instructions:
• An adequate two-pole switch must be inserted before the main outlet; this switch must be equipped
with time-delay fuses;
• The connection with ground must be made with a two-pole plug compatible with the above mentio-
ned socket;
• When working in a confined space, the power source must be kept outside the welding area and the
ground cable should be fixed to the workpiece. Never work in a damp or wet area, in these conditions.
• Do not use damaged input or welding cables
• The welding torch should never be pointed at the operator’s or at other persons’ body;
• The power source must never be operated without its panels; this could cause serious injury to the
operator and could damage the equipment.
3.0 INTRODUCTION
MATERIAL TO WELD GAS CYLINDER WIRE

Stainless steel Argon cylinder Stainless steel wire spool.
Aluminum Argon cylinder Aluminum wire spool
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 condition, inspect it carefully when you remove it from its packing
taking 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.

steel wire 0,8÷1,0 diameter (Gas Welding) and with flux core wires 0,8÷1,0 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
Feed rolls for Aluminum, U-groove 0,8-1,0mm for wires 0,8mm
Gas Selection
According to the material to be welded and to the wire you are going to use, select the shielding gas. The
