950981 - ESAB 24V DC Gas Solenoid Valve 1/4-Inch 2-Way NC

Precision Gas Control for Industrial Welding Systems

The ESAB 950981 is a high-performance solenoid valve engineered specifically for the demanding requirements of industrial welding equipment. As a genuine OEM component, this valve is designed to integrate seamlessly with ESAB power sources and wire feeders, ensuring that the shielding gas delivery system operates within the manufacturer's precise specifications. The unit features a 24V DC coil, a standard voltage for control circuits in modern welding machinery, ensuring compatibility and reliable actuation during the welding cycle.

Technically, this is a 2-Way Normally Closed (NC) valve. The "Normally Closed" designation is critical for welding safety and efficiency; it means the valve remains shut, blocking gas flow, until it is energized by the welding machine's trigger signal. This design prevents gas wastage when the machine is idle and ensures that shielding gas is only dispensed when an arc is struck or during programmed pre-flow and post-flow cycles. The 2-way configuration provides a simple on/off flow path, ideal for managing the supply of Argon, CO2, or mixed gases from the regulator to the torch.

The valve is equipped with 1/4-inch ports, a standard size that accommodates common fittings used in industrial gas plumbing. This facilitates straightforward installation and replacement during maintenance intervals. The robust construction of the solenoid housing protects the internal coil and plunger mechanism from the dust, vibration, and thermal fluctuations typical of a welding shop environment. By maintaining a tight seal when closed and opening instantly upon actuation, the ESAB 950981 plays a pivotal role in maintaining weld quality by ensuring the weld pool is adequately protected from atmospheric contamination at the exact moment it is needed.

For maintenance, repair, and operations (MRO) professionals, utilizing genuine ESAB parts like the 950981 ensures that the equipment retains its original performance ratings and reliability. Generic substitutes may not match the flow characteristics or response times required for high-speed automated welding or precision TIG applications, making this OEM valve the preferred choice for maintaining system integrity.
