33037 - ESAB 33037 Replacement Gas Orifice for PCC-90D/91

Precise Gas Flow Regulation for ESAB Plasma Systems

The ESAB 33037 Orifice is a critical internal component designed for the gas management systems of specific ESAB and legacy L-Tec plasma cutting consoles, notably the PCC-90D and PCC-91 series. In plasma cutting, the regulation of gas flow is paramount to achieving a stable, constricted arc capable of cutting through conductive metals efficiently. This orifice is precision-engineered to restrict and meter the gas flow to exactly 160 SCFH (Standard Cubic Feet per Hour), ensuring that the plasma torch receives the correct volume of gas for cooling and plasma generation.

Manufactured to strict OEM tolerances, this orifice prevents the common issues associated with gas flow variance, such as pilot arc sputtering, poor cut angularity, or excessive electrode wear. The orifice is typically installed within the gas plumbing or solenoid assembly of the power source or console. Over time, orifices can become clogged with particulate matter from the air supply or eroded by high-velocity gas flow, leading to a drift in flow rates. Replacing a compromised orifice with the genuine ESAB 33037 restores the system's pneumatic balance.

Technicians servicing PCC-90D and PCC-91 units should verify the integrity of the gas metering system during routine maintenance. A deviation from the 160 SCFH specification can lead to overheating of the torch head or failure to transfer the arc. This component is compatible with standard shop air or nitrogen, depending on the specific machine setup and cutting application. Its durable construction ensures long-term reliability in industrial environments.
