Razorweld ARC180 is an inverter-based welding machine produced using the latest in IGBT technology. This machine is reliable, robust and stacked with features that you can expect from UNIMIG. The DC MMA welding capability delivers a smooth and incredibly stable arc allowing easy welding with MMA electrodes producing high-quality welds on material such as cast Iron, stainless steels and mild steels. The machines is capable of running general purpose and low hydrogen electrodes with either VRD switched on or off by the key at the rear of the machine. This assists in the arc striking making it easy to run hard to start electrodes.

The Razorweld ARC180 is equipped with DC Lift TIG Arc function that allows quality DC TIG welding of mild steel, stainless steel, bronze, copper, and chrome moly. The Lift Arc function is superb and delivers perfect arc ignition which minimises the tungsten electrode sticking to the workpiece, a remarkably smooth stable arc produces high-quality TIG welds for a high-quality finish. The Razorweld ARC180 is an exceptional machine that is suitable for a wide range of applications including light industrial use, site welding, farming, along with repair and maintenance applications. This is packaged in a robust PVC carry case with your choice of MMA option accessories or MMA/TIG option accessories. This welder machine gives you great portability, with the power to get the job done. Built to our specification and manufactured in compliance with AS/NZ60974.1
