Expert TIG 302 AC/DC Pulse Pro5 LCD W is an IGBT inverter TIG power source supplied from three-phase 400 V mains. You use it for TIG and TIG Pulse with alternating (AC) and direct (DC) current, and for coated electrode welding (MMA). AC is for aluminium, its alloys and brass, and DC is for stainless, carbon and low-alloy steel, copper and titanium. This version is a complete set with a cooler, a trolley and a TIG torch with remote control.

Features
Welding modes
You can choose TIG DC, TIG DC Pulse, TIG AC, TIG AC Pulse, TIG spot, MULTITACK, TIG MIX, TIG RPT, as well as MMA AC, MMA DC and MMA Pulse. Pulse affects the weld shape and how focused the arc is, and less heat goes into the material, which helps on thin sheet.
TIG MIX, MULTITACK and waveform
TIG MIX combines direct and alternating current, which gives full penetration and effective cleaning on aluminium. MULTITACK is intermittent welding of the cold welding type, at a frequency of 0.5 to 6.0 Hz. You set the voltage waveform in AC and DC to square, triangular or sine, and in AC, MultiWAVE builds the characteristic from two curves.
Arc ignition and torch trigger
You strike the arc without contact (HF) or by contact (LIFT). Use LIFT where HF interference would affect the surroundings. The trigger works in 2T, in 4T with latch for long welds, or in RPT, which switches between two current levels. SPOT spot welding works only with HF.
LCD screen, synergy and SMART TIG
On the LCD touchscreen you set the whole cycle: gas, currents, rise and fall times, pulse, AC balance and frequency, HOT START and ARC FORCE. Every process has full synergy. In SMART TIG you choose the initial parameters, and the power source sets the output parameters to match them. DYNAMIC ARC keeps the weld width constant, and CAP SHAPING rounds the electrode tip to suit its diameter.
MMA and construction
In MMA you have ARC FORCE, HOT START and ANTI STICK, which switches off the voltage when the electrode sticks. The cooler protects the torch from overheating, and you connect the gas quick coupler without tools. There is overload protection and a semi-passive SMART fan mode.
