TIG/MMA Supertig 302 AC/DC welding machine, 3Ph 400V

This welding machine is a source of current for arc welding, manufactured specifically for TIG (AC / DC) welding with HF or LIFT strike and MMA welding of coated electrodes (rutile, acid, basic).

In alternating current, TIG AC allows you to weld aluminium and its alloys (AlSi, AlMg), while in direct current, TIG DC allows you to weld steel (carbon, stainless, low alloy and high alloy) and heavy metals (copper, nickel, titanium and their alloys).

The specific characteristics of this welding machine (INVERTER), such as the high speed and adjustment precision give excellent welding quality.

Adjustment with the “inverter” system on the power line input also determines a drastic reduction in volume both of the transformer and the levelling reactance, allowing 
manufacture of a welding machine with extremely contained volume and weight, enhancing its manageability and movement.

Main features

• Use with different types of materials such as steel, stainless steel, aluminium, titanium, copper, nickel, magnesium and their alloys.
• Designed to ensure excellent results on every thickness even the thinnest, the PULSE mode (also in the EASY PULSE version) reduces material deformation ensuring high arc stability.
• Presence of advanced features: MIX AC-DC for preparation of AC welding of workpieces with considerable weights; THINSPOT for spot welding of very thin sheet metal.
• The LCD screen facilitates interaction with the product and simplifies adjustment of multiple parameters of the TIG welding curve depending on processing needs.
• You can save and retrieve customised programs.
• Electrode welding both in continuous and pulsed mode (MMA Pulse) which ensures excellent results with basic electrodes and in position welding.
• Designed for reliability over time, it features a dedicated air tunnel cooling system that protects against dust and dirt.

TIG WELDING FEATURES
