Arc Machines introduces the Arc Machines Model 415, a versatile welding automation control and power supply system. The standard Model 415 can be used to weld all alloys that are weldable with the Gas Tungsten Arc Welding process (GTAW, or TIG) using straight polarity DC current. The basic Model 415 features a complete complement of controls, water cooling and gas control necessary to operate all AMI orbital weld heads for in-place field welding tasks ranging from small diameter fusion tube welds to heavy-duty piping and vessels.
