AC Best inverter tig welder machines utilize high current electronic switches, generally IGBT, to make an AC weld yield. The AC recurrence can be changed ordinarily to 30-150Hz.
A high-recurrence AC can center the curve, which is helpful on thin material and sharp corners. Excellent control of AC balance or the positive cycle’s measure to the damaging process is significant. Changing the equilibrium is essential for affecting the extent of surface cleaning the bend performs.
