-While welding,the through hole positioner is convenient for the pipe to be clamped and positioned,so it has improved the accuracy degree of welding.
-While the pipe is welded,the through hole positioner will protect the gas when it go through the internal pipe,then it has improve the efficiency and quality of welding.
-The main shaft can be turned 90°clockwisely and anti-clockwisely, to fit any welding angle.-The turning structure of worm and gear has the function of self-lock.
-Special design of anti-electromagnetic, which reduces the high frequency interference of TIG's welding,and can improve the welding quality effectively.
-The track and air-powered tip can be furnished to achieve the function of self- holding to the workpieces.
-Track can be extended according to your requirements.
