KHGK Caliper type pipe-pipe argon arc welding machine
KHGK series pipe-to-pipe fully automatic pulse argon arc welding machine is specially designed for all-position automatic welding of pipes with an outer diameter of 16 to 300mm. The entire set of equipment is independently developed by our company. It adopts advanced inverter DC pulse argon arc welding power supply, vehicle-mounted integrated design, touch screen data input, and PLC module control system.


boilers, heat exchangers, chemicals, food, medical, engineering installation, industrial pipelines, ships, military industry and nuclear power industries.



Other types:

1. 5 specifications, select as needed; caliper-type clamping is quick and convenient, and can be adjusted arbitrarily for different pipe diameters;

2. The main components of the machine head are made of aviation materials, which are light in weight, stable in structure, and will not deform at high temperatures; using a stepper motor, the machine head moves stably and reliably;

3. PLC control system can store up to 100 sets of welding specifications, and each set of welding specifications can be divided into 1-12 segments; LCD touch screen makes input simple and convenient;

4. Using Panasonic IGBT inverter controlled DC pulse power supply, the welding efficiency is high, the arc is stable, and the weld bead shape is beautiful;

5. Forced water cooling system, equipped with a 16-liter stainless steel water tank, which circulates the welding torch for cooling, and the machine can work continuously for 24 hours;

6. Car-mounted integrated design, free to move.
