New Transmigs have been designed as tough and stable power sources designed to withstand use in an industrial environment. The 326S, 406S and 406SW are conventional MIG/MAG/FCW power sources for MIG, MAG and flux cored wire-welding applications. They use simple three-phase switch and tap technology to produce reliable performance for applications up to 400A. The 406SW model incorporates a MIG torch water-cooling unit. Operating from a standard 415V three-phase supply, it provides a wide-ranging welding performance from 50 to 400A at 50% duty cycle with 406S model. 40 voltage selections in combination with two levels of inductance give very precise control of the welding setting and excellent welding characteristics. Both Transmig 326S and 406S/SW have digital volt and ammeters and are supplied with removable gas cylinder trays, feeder swivel mounting post and work return lead. The digital meters feature last reading hold. Combined with either the Murex Transmatic Lynx 2 or 4HD wire feed unit and the matching MX MIG torch, the new power sources are available as a MIGPAK industrial package.
