0191510104 - ESAB MigMaster Spot Weld Timer Knob Replacement

Restore Precision to Your ESAB MigMaster

Don't let a broken or missing control knob slow down your fabrication work. The ESAB Spot Weld Knob (0191510104) is the direct replacement part you need for your MigMaster welding machine. Designed to control the spot weld timer function, this knob is essential for welders who rely on precise timing for stitch welding or repetitive spot welding applications. When your equipment controls are intact, your workflow remains smooth and uninterrupted.

This is not a generic "one-size-fits-all" component. It is a genuine ESAB part, meaning it is manufactured to the same rigorous standards as the original knob that came with your machine. It fits securely onto the control shaft of the MigMaster 173, 203, and 253 models, eliminating the frustration of loose dials that spin without changing settings. A secure fit ensures that when you dial in a setting, the machine responds exactly as intended.

Why Choose OEM Replacement Parts?

Welding machines are investments, and maintaining them with OEM parts protects that investment. Generic knobs often lack the internal reinforcement to handle the torque required to turn stiff potentiometers, or they may not align correctly with the panel markings. This ESAB replacement knob features:

• Exact Shaft Fitment: Prevents slippage and ensures accurate parameter adjustments.
• Rugged Construction: Made from durable materials capable of surviving the harsh environment of a metalworking shop.
• Original Aesthetics: Keeps your MigMaster looking professional and well-maintained.

Quick and Easy Repair

Replacing a control knob is one of the simplest repairs you can perform, yet it makes a massive difference in usability. Simply remove any remnants of the old knob and slide or secure this new unit onto the shaft. It is an affordable fix that immediately improves the ergonomics and functionality of your welder. Whether you are a hobbyist with a MigMaster 173 in your garage or a professional shop running MigMaster 253s, keeping spare knobs on hand is a smart way to avoid downtime.

Get your machine back to 100% functionality with the ESAB 0191510104 Spot Weld Knob. It’s the small part that makes a big difference in your daily welding operations.
