Product Details
Description and specifications

The Razorweld 250 is the ideal machine for light to medium industrial fabrication work . The machine is single phase 240V and also portable and perfect for site work. The MIG function provides superb arc characteristics when using either Gas Shielded or Gasless Wires. The machine features an adjustable Burnback control and easy to use panel layout to get your job done faster.

The machine is also a very capable MMA (Stick) welder capable of running most MMA Electrodes up to 4.0mm. An added feature of Hot Start helps when striking an Arc to minimise the Electrode sticking to the work piece.

With the machine being Spool Gun ready a UNIMIG Spool Gun is available if you want to run Aluminium wire without the changeover in the torch, liner and drive roller. The Spool Gun is an ideal way to use softer wires and not have to purchase larger spools of wire for small jobs.

The Razorweld 250 is also a DC TIG welder with Lift Arc function. DC TIG will allow welding of materials such as Mild and Stainless Steels as well as Bronze, Copper and Chrome Moly’s.

*Always refer to the recommended polarity setup as stated on the electrode packaging.
