The ESAB 40V01 is a specialized conduit assembly designed for the maintenance and repair of ST-21M MIG welding guns. As a critical component in the wire feeding path, this conduit—often referred to as a liner—ensures the mechanical stability and smooth transit of welding wire from the feeder to the contact tip. It is engineered to precise tolerances to accommodate 5/64-inch (approximately 2.0 mm) diameter wires, a common size for heavy-deposition industrial applications.
Constructed to withstand the rigors of continuous industrial use, the 40V01 conduit minimizes friction coefficients inside the cable assembly. High friction in the liner is a primary cause of erratic arc performance, wire chatter, and premature wear on drive rolls. By maintaining a clean and unobstructed path, this genuine ESAB part supports consistent electrical conductivity and arc stability. The 6-foot length is tailored to the standard cable configuration of the ST-21M torch, ensuring a seamless fit without the need for modification.
Regular inspection and replacement of the conduit are recommended as part of a preventative maintenance schedule. Accumulation of metal shavings, lubricant debris, or shop dust within the liner can impede wire feed speed. Installing the 40V01 restores factory-level performance to the wire delivery system, making it an essential stock item for facilities utilizing ESAB ST-21M equipment for structural or heavy fabrication tasks.
