The Razorweld 180 DC MMA/TIG is a professional MMA/TIG Inverter capable of producing high quality welds. The machine is fitted with a 15 AMP plug as standard. The machine also features keyable VRD (Voltage Reduction Device) which is a benefit when wanting to run Low Hydrogen Electrodes. The Razor ARC 180 can run MMA Electrodes up to 4.00mm*.

The Razor Arc 180 also has the feature of Lift Arc TIG. Lift Arc is a form of arc ignition that is simple, safe and is far superior to scratch start.

Lift Arc ignition allows the arc to be easily started by simply touching the tungsten to the work piece then lifting it up to start the arc. This prolongs the Tungsten Electrode’s lifespan and helps maintain a clean Tungsten.

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