As part of the MIG, TIG and Stick line from Everlast, the PowerMTS 400 falls into the CC/CV power source class. This means that the inverter power supply is not incorporated into the wire feeder section. This allows the unit to be used exlusively for one type of operation for maximum portability. The main unit of the PowerMTS feeds power directly into a separate wire feeder for MIG, making extremely convenient to port around on large job sites. The unit can be used for stick welding as well, and features hot start and arc force control strong enough to burn in any root pass with E6010, or any 6010 variation such as 5P+ without sticking or the arc trying to extinguish. This unit is made for industrial and commercial applications and smaller welding shops as well. The dual voltage, dual phase technology allows the unit to be used with single phase 240V or three phase 480 (output is decreased on 240V). With up to 400 amps of welding power @ 60% Duty Cycle thisindustrial unit doesn't quit. Compared feature to feature with other CC/CV powersource-MIG systems on the market such as XMT® from Miller and Invertec® from Lincoln, the unit packs more overall features and performance at a price that is well less than the competition. The basic design of the unit includes special settings for scatch start TIG, Flux-Core, MIG, Stick. A separate setting for Air-Carbon Arc Gouging/Cutting is also provided. The PowerMTS 400 have been carried onto oil platforms, pipelines, and into fabrication shops and portable repair buisnesses. The potted and coated boards and terminals protect the electronics from damage and corrosion from the elements. As a complete package, the PowerMTS 400 comes with wire feeder, clamps, cables, torches, and even a convenient welding cart. Even if you don't need it all, and need only the MIG feature, this unit works well as a stand alone unit in any shop or or on any worksite.

Heavy Duty CC/CV Inverter Power Source reduces the amount of units needed in a shop or on a worksite to handle large jobs
5 individual settings for Mig, Flux Core, DC Tig, Stick and Carbon Arc Gouging
Everlast's largest industrial welder to date, part of the new Heavy Industrial lineup, performs well against competitor's product such as the Miller XMT® and Lincoln Invertec® CC/CV
Boards and sensitive electronics are either coated or potted to resist moisture, dirt and shock
High Duty cycle performance at maximum amps improves production.
Adjustable MIG arc force/inductance control precisely manages the arc characteristics to produce the best possible weld
2T/4T torch trigger/latch function offers stepped control welding with MIG with crater fill amps and volts to finish off a perfect weld
The MTS 400 is capable of powering the M 600 wire feeder (included) up to 175 feet away so only the wire feeder needs to be carried into position.
The M 600 wire feeder adjusts both volts and wire feed speed directly on the feeder without having to return to the power source to change settings
The M600 wire feeder includes an inching button and a heavy duty gear driven wire feed mechanism with 4 drive rolls to power feed large diameter wire
Hot Start and excellent arc force control makes burning pipeline rods such as 6010 5P easy.
Scratch Start DC TIG offers the same precise, smooth arc of other Everlast inverter welders
A special optimized setting makes Carbon Arc gouging easy (recommended for use only with 480 V 3 phase only for best results)
Crater fill Volts and Amps for MIG yield high quality MIG results to prevent end weld cracking
12ft. 17 V (gas valve) Series TIG torch
Features 12 ft. Heavy Duty 36 series NORTH MIG gun with Euro Quick connect fitting
Stick electrode holder with cable
Work clamp with cable
Rolling Cart that integrates both wire feeder and power source with room for gas cylinder
Everlast M600 wire feeder
Wire feeder connection cables, up to 20ft.
