The head is suitable for automatic welding of tubes/pipes in narrow pitch form.It can weld various pipes/pipes such as carbon steel and stainless steel.The diameter of the tube ranges fromφ32mm-38mm,and two methods of filling wire or self-melting can be selected.The arc length can be adjusted automatically,and it has a yaw function.It can be used in conjunction with iOrbital5000 programmable welding power source,which can precisely realize orbital TIG tube/tube welding,with high reproducibility of welding results and ideal welding results.Mainly used in chemical,food,boiler, and nuclear power industries.
