Inverter welder MTM 251/4R

Inverter welder MTM 251/4R The MTM 251 welder is a compact universal inverter device made with MOSFET technology. It is used for welding steel and non-ferrous metals with covered electrode (MMA method), TIG method, as well as MIG/MAG method using standard MIG/MAG welding chuck and Spool gun. It allows MIG/MAG welding using both standard shielded gas wires and self-shielded powdered wires. The device is equipped with a professional 4-roll wire feeder with infinitely adjustable feed speed, infinitely adjustable welding voltage for MIG/MAG welding and welding current for MMA and TIG welding, as well as non-contact ionization arc ignition for TIG welding. It has adjustable current rise and fall and gas delay. It also has a 2T and 4T switch, welding current/voltage displays and inductance adjustment for welding thin and thick workpieces. It works with K-200 (5kg) and K300 (15) kg wire spools.
