The Snap-on MIG Welder, No. MM250SL, has higher duty cycles at maximum amperage for longer, continuous weld times. It features exact voltage settings for precise heat control and ease-of-use while the detachable feeder allows ease of mobility and features wire speed controls for fine tuning. The capacitor bank and diode set deliver consistent voltage and industry-leading smooth-arc characteristics, according to the company. It also offers the ability to add a SpoolGun for aluminum welding or TIG Accessory Pack for ferrous metals.
