Lincoln Powerwave i400 Overview The Lincoln Powerwave i400 robotic welding supply is capable of performing MIG welding, TIG welding, STT welding, as well as various other advanced welding processes. The i-400 can communicate with the FANUC RJ3IC, FANUC R30ia, and FANUC R30ib controllers. The Lincoln Powerwave i400 is a great choice for automated, semi-automated, and robotic welding. Very similar to its predecessor the Powerwave 455m, the Powerwave i400 integrates with most used welding robots to provide a ready to weld solution. The i400 is commonly integrated with the FANUC Arcmate 100ic, the FANUC Arcmate 100ic 6L, and the FANUC Arcmate 120ic.
