Designed for automatic TIG welding of special pipes and tubesheet, it is suitable for automatic welding of tubesheet of high and low pressure vessels, boilers, heat exchangers, etc., and can be welded with titanium alloy, stainless steel, carbon steel and other materials. The welding method is pipe flat head, pipe extended welding, wire adding welding and self-fusion welding without wire filling. The welding speed is fast, the weld seam is beautiful, and the weld quality is high. The LD-400 welding power supply is used as a complete set. The welding range of pipe fittings is<1>16 φ 76. Pipe flat welding and pipe extended fillet welding can complete.
The hollow cup DC motor and high-performance encoder are used to accurately count the welding rotation, adopt three-claw and pneumatic core expansion positioning, and the gun body has its own wire feeding structure. It can realize welding with or without wire filling. The 1Kg welding wire disc is used as the welding wire disc, and the pigeon pole is of standard diameter φ 2.0-φ 3.2mm pigeon pole, welding cooling water, protective gas, conductivity and wire feeding are all of non-winding design, easy to operate, light weight, small size and other characteristics.
