WELDER HAVING GAS FLOW FEEDBACK CONTROLMETHOD OF PROVIDING A TARGETED SHIELDING GAS FLOW RATE TO A WELD SITECORRESPONDING GAS FLOW FEEDBACK CONTROL

摘要

Disclosed is a method and system for improving flow control of a protective gas in a welding unit, wherein the controller is utilized using feedback from at least one of a mass or volume flow controller 50, a pressure sensor 52 and a valve position sensor 54. The protective gas flow through 50 is regulated.
