ESAB Victor 0781-4253 GT350-60-320 Heavy-Duty Two-Stage Carbon Dioxide Regulator CGA-320

The Victor GT350-60-320 (MPN: 0781-4253) is a heavy-duty, two-stage carbon dioxide regulator designed for professional welding and cutting applications requiring precise, consistent CO2 gas delivery. Featuring a CGA-320 inlet connection, this regulator is the standard choice for CO2 cylinder service.

Two-Stage Design Advantage:

Unlike single-stage regulators, the GT350's two-stage design eliminates pressure creep — a condition where delivery pressure rises as cylinder pressure drops. The first stage reduces high cylinder inlet pressure down to a preset intermediate level, while the second stage delivers exceptionally consistent and accurate output pressure regardless of how full or empty your cylinder is. This results in more stable gas flow, less wasted gas, and higher quality work.
