Tig electrode grinder is a precision grinding machine for tungsten electrodes. This unit has a patented electrode holder allowing easy grinding, which results in a centric and longitudinal grind. Small diameter electrodes are held against the wheel, preventing out of round grinds. A tungsten electrode grinder is necessary to get proper arc penetration especially when using orbital welding machines. Tig welding process requires a pressurized supply of a suitable inert gas from cylinders or bulk containers and cables of the correct size to conduct welding current from the power source to the torch.
