Harris releases regulator for shielding gas

Harris Products Group’s Model 351 “zero” compensated flowmeter regulator for use with shielding gas protects the weld puddle against contamination from atmospheric air and other elements that can cause weld defects. The device utilizes a ball float and a variable area flowmeter to yield precise control of the welding gas. The control valve is strategically placed on the upstream side of the flowmeter, which means that it can operate accurately at virtually any inlet pressure. This design also significantly reduces the surge associated with pressure compensated flowmeters allowing it to also function as a gas saving device.
