Abstract

Systems and apparatus are disclosed relating to improved fluid supply systems. In some examples, the improved fluid supply systems use an electrically controllable proportional valve and a surge prevention process to prevent a surge of pressurized fluid at the end of a welding-type operation. In particular, the surge prevention process may coordinate closure of the proportional valve and an on/off solenoid valve so that pressure in the fluid flow path can equalize to an ambient pressure after a welding operation (and/or a post flow operation) has ended. This coordination ensures that there is no pressure buildup and/or associated surge of fluid when the on/off solenoid valve is next opened (e.g., at the start of the next welding operation).
