1. Automatic argon arc (plasma) girth welding mainly by a specially designed girth machinery automation standard configuration of the power section and section 2. Depending on the specific welding workpieces, machinery automation section contains: Horizontal girth automation and Vertical girth automation. By special design and manufacturing company. 3. The standard power section includes: TIG (Gas tungsten arc welding), MIG (metal inert gas shielded arc welding), MAG (metal active gas shielded arc welding), SAW (submerged arc welding), PAW (plasma welding ) and so on. Manufactured by the company can be equipped with high quality standard power supply, while customers can also use other well-known brands to power, versatility is very strong. 4. workpiece rotation by inverter motor + reducer + driving mode clamping jaw, smooth motion, variable speed. 5. compression axis pressing and releasing the torch back and forth and are used cylinder drive, and the gun with precision micro-adjustment mechanism, so that the best position to form the weld torch. 6. The control system uses a microcomputer integrated control, small size, reliable and simple user interface, modify and easy maintenance. Rated input power 220V / 380V / 440V / 480V, 50 / 60Hz 50W-1500W motor power supply pressure 0.4-0.6Mpa maximum diameter of 488mm workpiece welding speed 200-1000mm / min
