Inner Water-Cooling Electrode for Bolt Welding is a electrode holder for bolt welding which water circulate through the electrode, it offers increased cooling efficiency while it is slim shape.
A water jacket would improve cooling, but However, it is too bulky to be used in tight spaces.
The "Internal Water Cooled Electrode with Bolt" is the solution to this problem.
Cap for bolt welding
Electrode tip is replacable, only the tip part needs to be replaced depend on bolt size you use (suitable for M4・M5・M6・M8 ).
Hole for air blow reduces spatter blockage.
Suitable for bolts with a length of 35 mm or less below the head.
