The ESAB ST-21 is a handheld water-cooled MIG (GMAW) gun designed for continuous industrial production and extreme-duty applications. It utilizes a liquid cooling system that circulates coolant through the power cable and torch body to manage high thermal loads. The system is compatible with the 85W08 single-pole single-throw (SPST) switch for high-amperage torch control.
