Coplay Norstar N810200M-I Dual Voltage Input Mig Welder, 115/230 VAC, 90/150 A, 50/60 Hz

M200i-M welder package comes ready to weld, simply add shielding gas. Uses both 4 and 8 in spools. It offers infinite voltage and wire speed controls, is truly spool gun ready and uses industry standard consumables. New inverter controlled power supplies in which the output control is performed by solid state controls that modulate the switching rate of the switching transistors. Providing advantages like the main power transformer, which operates at 20000 Hz is vastly more efficient that 60 Hz transformers, which means it can be much smaller and lighter. Inverter equipment is also much more efficient than transformer equipment. Voltage compensated wire control offers all the benefits of a standard MIG machine but adds the ability of the wire speed function with the output voltage selected. This function allows the operator to focus the welding controls to the wire diameter and the material thickness. This feature allows for a smooth spatter free start.
