WSM7 Series of IGBT Inverter Pulse TIG Welding Products

Features

■ Adopt the soft switch technology, high efficiency, low power consumption

■ Automatic protection from overcurrent, overheat, over/under voltage

■ Support DC TIG welding, pulse TIG welding and MMA welding, can weld such metals as stainless steel, alloy steel, copper, silver, titanium, etc.

■ In TIG welding, can select DC or pulse welding according to the requirements, can adjust the peak/bottom current, pulse duty circle and frequency according to the size of welding seam

■ In TIG welding, HF automatically strikes arc, and extinguish automatically after the arc is successfully stroke, high efficiency

■ With the long/short seam switch and gas/water cooling switch, can make selection according to the actual need

■ In MMA welding, suitable for the electrode with a diameter of below 5.8mm

■ Can realize TIG grounding and MMA covering once a time, high efficiency, especially suitable for the welding of thin rare-metal board

■ Wide range of supply voltage, as wide as ±20%
