The Hugong NVT233ACDC is a high-end digital TIG welding machine designed for both AC and DC applications. This machine is part of the NOVI line and offers advanced 4-in-1 functionality: HF TIG AC, HF TIG DC, Lift-TIG, and MMA. It’s powered by next-generation IGBT inverter technology and a Cortex M4 chip, providing precise and reliable control over the welding process.
The NVT233ACDC features full TIG functionality including pulse control, gas pre-flow and post-flow, slope up/down, and 2T/4T operation. In MMA mode, the device includes Arc Force, Hot Start, and Anti-Sticking features. The AC ARCARE system ensures smooth arc stability and is ideal for thin sheet applications or spot welding. Thanks to the PFC module, the machine can handle wide voltage input ranges from 95–275V, making it suitable for unstable power grids or mobile power sources.
With its HDVision control panel, you get intuitive access to all parameters on a crystal-clear display. Its robust design with ABS shock-resistant housing makes it a durable choice for demanding workshops.
This unit is ideal for welding carbon steel, stainless steel, copper-silicon alloys (CuSi), and aluminum.
