An electrode holder, commonly called a stinger, is a clamping device for holding the electrode securely in any position. The welding cable attaches to the holder through the hollow insulated handle. The design of the electrode holder permits quick and easy electrode exchange. Two general types of electrode holders are in use: insulated and noninsulated. The noninsulated holders are not recommended because they are subject to accidental short circuiting if bumped against the work- piece during welding. For safety reasons, try to ensure the use of only insulated stingers on the jobsite.
Electrode holders are made in different sizes, and manufacturers have their own system of designation. Each holder is designed for use within a specified range of electrode diameters and welding current. You require a larger holder when welding with a machine having a 300-ampere rating than when welding with a 100-ampere machine. If the holder is too small, it will overheat.
These fully insulated Electrode Holders are made to withstand adverse welding conditions such as ship building, fabrication, construction and dockyard. The Electrode Holders also find application in welding of enclosed conditions including vessels. Special ergonomic designs make the holder safe and comfortable for longer welding hours. These designs help in providing easy and effective connection of cable to holder. The use of non ferrous metallic alloy for its manufacturing jaws ensures transmission of 100% current to the electrode.
