Multi-functional trolley column handles every combination... Prizewinning design that can carry a little extra Extra wire-feed unit: e.g. Pi 200/250 or Zeta 40/60 The unique “backbone” can be used for a double version with two wire-feed units or a triple version combining Sigma2 (MIG/ MAG) with Migatronic Pi (TIG) or Zeta (plasma cutter). Sigma is characterised throughout by Migatronic's new design, which received the iF Product Design Award. New intelligent Sigma2 advantages: • Intelligent Gas Control IGC® • ncreased memory with the I possibility of more program packages • D card for...

Custom-built solutions - Sigma2 is configurable for any welding application Power supply via autotransformer Portable wire-feed unit with industrial wire-feeding It is a question of functionality and high performance under all voltage conditions. With an autotransformer incorporated in the “chassis” of the multifunctional column, the Sigma2 is safeguarded against undesirable voltage fluctuations in the 230500 V range. For Sigma2, Migatronic has developed the MWF 41, a compact, portable wire-feed unit (30 m/ min. wire-feed speed), that combines the limited dimensions of the open type with...

Automated welding with Sigma2 in a complete robot setup Robot interface Robot concept – fully operational with all units RWF Multi The two largest Sigma2 machines in “automated trim” are designed for integration with robots and automated devices along with RWF Multi. I/O robotinterface is the communication interface between the CAN-BUS power source and robot or automated device. RWF Multi is a wire feed unit that feeds wire from a spool or drum through an intermediary cable into the robot torch. RWF Multi can also be used as a separate wire-feed unit with wirereel holder for manual welding...
