Chief Introduces Three-Phase, High Amperage MIG/MAG Welder

The MultiMig 621 can be used to weld and braze aluminum, galvanized sheet metal, stainless steel and high-strength steel.

chief-multi-migChief has expanded its line of inverter synergic pulse MIG/MAG welders to include its first three-phase, high-amperage model, the MultiMig 621. The MultiMig 621 can be used to weld and braze aluminum, galvanized sheet metal, stainless steel and high-strength steel.

Like all Chief MIG/MAG welders, the MultiMig 621 features the synergic-pulsed technologies required by most OEMs for aluminum welding. It has a double pulse feature that allows the weld to cool slightly during the low-frequency operation. This is an important characteristic when welding vertically or overhead, as it reduces the chance of drips. It also reduces deformation on thin pieces while providing full penetration on thicker sheets.

The MultiMig 621 comes loaded with a large number of synergic programs that preset welding parameters so technicians can start welding immediately. Multiple programmable options, such as crater fill and hot start, are also available to customize the welder’s operation to meet specific customer needs, working conditions and technician preferences.

The MultiMig 621 can produce up to 275 amps of output power versus 200 amps provided by the Chief MultiMig 511 and 521 welders. Its three-phase power source provides smoother operation for smoother welds. It’s available with either a standard MIG torch or Chief’s unique push-pull torch. This lightweight torch features fingertip wire-speed and current level controls, as well as a push-pull system that maintains constant, uniform tension on the wire, minimizing breakage or tangling.

The MultiMig 621 is multi-input line voltage capable and able to run on any voltage from 200 to 480 volts. It features Integrated Power Factor Correction (PFC) technology to reduce energy waste, and is equipped with a built-in cart that includes storage space for a gas cylinder.
