31W18 - ESAB CM-30 Blowpipe Holder Adjustment Knob

Restore Precision to Your ESAB CM-30

The ESAB 31W18 Knob for BP (Blowpipe) Holder is a critical replacement component designed specifically for the ESAB CM-30 portable cutting machine. In the realm of automated and semi-automated oxy-fuel cutting, the stability of the torch is paramount. The CM-30 is a workhorse in the industry, known for its durability and precision in straight-line and circle cutting. However, the mechanical components that secure the torch—specifically the blowpipe holder assembly—are subject to wear and tear over time due to frequent adjustments and the harsh thermal environment of cutting operations.

This replacement knob serves a vital function: it allows the operator to manually tighten, loosen, or adjust the position of the blowpipe holder. A worn or missing knob can lead to a loose torch, resulting in wandering cuts, bevel inaccuracies, or even safety hazards if the torch shifts unexpectedly during a burn. By installing a genuine ESAB 31W18 knob, you ensure that the clamping mechanism functions as intended, maintaining the rigid alignment necessary for high-quality cuts.

As an OEM (Original Equipment Manufacturer) part, this knob is manufactured to the exact specifications of the original machine. This guarantees correct thread pitch, diameter, and material strength, eliminating the frustration of trying to fit generic hardware onto specialized industrial equipment. The knob is designed for easy manipulation, often featuring a textured or ergonomic surface that allows operators to make quick adjustments even while wearing heavy welding gloves. Maintaining your CM-30 with authentic parts extends the service life of the machine and protects your investment in high-performance cutting equipment.

Whether you are performing routine maintenance or repairing a damaged unit, the 31W18 is the exact part required to restore the functionality of the blowpipe holder assembly. It is an essential spare to keep in your maintenance inventory to prevent downtime caused by minor hardware failures.
