WELPRO PRO MMA 160S 10-160A Inverter Welding Machine

The WELPRO PRO MMA 160S is a professional 160A Inverter Welding Machine designed to overcome the challenges of demanding welding applications with intelligent technology. Powered by the Synergic MMA Function, its semi-automatic welding parameter adjustment system makes welding easier and more convenient for users of all skill levels

The machine delivers excellent energy efficiency, consuming up to 40% less energy and electrical current than conventional inverter welding machines. It is also designed to operate reliably under unstable power conditions, even when the input voltage drops to as low as 110-115V, while still allowing continuous welding with 3.2 mm electrodes

The PRO MMA 160S is compatible with generators available on the market, even when the generator has a Total Harmonic Distortion (THD) above 20%. It also features the newly designed WELPRO Super Connector, providing enhanced all-around electrical safety and protection against sparks and accidental electrical contact

Ideal for structural welders, maintenance technicians, industrial applications, and demanding fieldwork
