April 24, 2016—Chief Automotive Technologies has expanded its line of inverter synergic pulse MIG/MAG welders to include its first three-phase, high-amperage model.
The MultiMig 621 can be used to weld and braze aluminum, galvanized sheet metal, stainless and high-strength steel.
The welder features the synergic-pulsed technologies required by most OEMs for aluminum welding. The MultiMig 621 has a double pulse feature that allows the weld to cool slightly during the low frequency operation.
The MultiMig 621 can produce up to 275 amps of output power vs. 200 amps provided by the Chief MultiMig 511 and 521 welders. The MultiMig 621 is available with either a standard MIG torch or Chief's unique push-pull torch.
The MultiMig 621 is multi-input line voltage capable: It can run on any voltage from 200 to 480 volts. It features Integrated Power Factor Correction (PFC) technology to reduce energy waste.
