Full product details
The SIP WELDMATE® PRO 120A DC TIG/ARC Inverter Welder is a dual process professional welder designed for fabrication workshops, sheet metal applications, and home workshops. Combining TIG DC and ARC (MMA) welding in one compact, portable unit, it delivers precision, reliability, and efficiency.
Equipped with high frequency (HF) start-up, this welder allows easy arc striking without electrode contact, resulting in cleaner welds, improved quality, and reduced risk of tungsten contamination. This makes it especially suitable for thinner materials where precise control is required. A built-in post gas function ensures weld integrity by protecting the molten weld pool and tungsten electrode from oxidation after the arc is extinguished.
The intuitive LED control panel with infinitely variable dials enables smooth stepless output adjustments, ensuring accurate settings and consistent weld quality. Powered by a 4th generation inverter with over 80% energy efficiency, the PRO 120A reduces power consumption while delivering strong performance from a standard 230v/13A supply.
Built with a robust metal casing and heavy-duty carry handle, it is compact, lightweight, and durable enough for workshop environments.
