636868 - ESAB ST-23A Inch Switch Mounting Disk

Restore Your ST-23A Torch to Peak Performance

Keep your welding operations running smoothly with the ESAB 636868 Disk Mounting Inch Switch. If you are operating the legendary ST-23A MIG gun, you know it is a workhorse designed for serious fabrication. Over time, moving parts and control mechanisms can wear out due to repetitive use and exposure to the harsh conditions of a welding shop. The inching switch assembly is frequently used during wire spool changes and setup, making it a common wear point. This replacement part is the exact solution needed to fix loose, broken, or malfunctioning switch mounts.

The "inching" feature on a MIG gun is a convenience that professionals rely on. It allows the welder to feed wire through the liner and contact tip without activating the welding power source or gas solenoid. This is crucial for safety and economy. If the mounting disk for this switch is cracked or the switch itself is loose, the feature may fail, forcing welders to use the trigger (which makes the wire "hot") or go back to the feeder to jog the wire. Installing the ESAB 636868 resolves these issues immediately, putting control back in the welder's hand.

Don't let a small part stop a big job. This kit includes the specific mounting disk required for the ST-23A configuration. Installation is straightforward for those familiar with torch repair, fitting directly into the handle assembly without the need for modification. By choosing this genuine ESAB replacement, you are ensuring that your torch retains its ergonomic feel and operational safety. Welders Supply is your source for hard-to-find parts for legacy and modern equipment alike.
