TIG welding machine HKTIG250C

Durable, attractive design

Hong Ky HKTIG250C Cold TIG Welder features an attractive design with a prominent yellow tone, weighing 10.5 kg. All four corners of the front and rear panels are fitted with protective plastic covers against impacts, making the machine solid and strong. The front panel is scientifically arranged, convenient for users.

Powerful performance - stable welding current

Using IGBT technology to stabilize the arc during high-power welding.
Operates on single-phase 220V AC input, with an output current of 250A.

Advanced welding technology - wide application

Cold TIG welding with precise control of welding time; heat input is intermittent, helping to reduce material burning, warping, and deformation.
DC TIG welding provides beautiful, slag-free, high-quality welds.
Tungsten electrode diameter 1.6 - 3.2 mm.
Welds materials such as iron, steel, low-carbon steel, copper, stainless steel, titanium, especially thin materials requiring minimal deformation.
Widely used in industries such as vehicle frame welding, furniture, shelving, medical equipment, food industry, electronics, and suitable for craft production workshops.

Modern features – maximum support for welding professionals

Pre-Gas and Post-Gas control: Pre-set pre-gas time and adjustable post-gas time after releasing the trigger, protecting the weld from oxidation, maintaining strength and aesthetics, and extending tungsten electrode life.

Flexible welding torch for multiple angles

Comes with a TIG torch WP-26F with a flexible neck, allowing bending at different angles to easily weld in difficult positions where rigid torches cannot reach.

Smart power saving

Inverter control technology saves electricity and optimizes working efficiency.

Overload/overheat warning light

Warning lights will automatically illuminate, helping users promptly detect issues and take corrective action.
