The Snap-on Synergic Double-Pulse Inverter MIG Welder, No. MIG200i, offers a welding current up to 200A, and pulse and double-pulse settings help provide increased control with even thin materials. Multiple, preset synergic curves automatically deliver optimal amperage, voltage and wire speed parameters for each individual situation, the company says. Selectable start modes include start current and crater fill options. The tool also features an easy-to-read LCD display panel that shows all welding parameters, with a single knob for selection and adjustments.
