Eastwood Elite


All-In-One Eastwood Welder

When you want a Multi-Process machine that's built to deliver great results with no compromises, you need the Eastwood Elite MP250i. It has all of the features of a standard DC TIG Welder like High Frequency Start and a Rocker Style Foot Pedal so when you switch from MIG to TIG you know you're going to get the same great results you'd expect from a dedicated TIG machine.

When you're doing a full-scale auto restoration, sometimes one welding function, whether it’s MIG or TIG, isn't going to be enough. This machine is completely plumbed for MIG and TIG welding, and the cart holds a gas bottle for each so you can almost instantly switch between functions without changing hoses and regulators like you would with other units. That means everything stays connected and ready to weld, and with a flip of a switch you can go from MIG to TIG welding when you're working on body panels, roll cages, custom-fab parts or other work.

Weld thin sheet metal or up to ½-inch steel plate using these versatile machines. The Elite MP250i doesn't stop there either. You can also stick weld aluminum or add an optional spool gun for MIG welding aluminum.

The Eastwood MP250i Multi-Process 250 Amp Welder Features:

  • Operates on either 120 or 240V
  • Welds steel and stainless
  • Welds aluminum, with optional spool gun
  • IGBT inverter based power supply
  • MIG Welds thin steel sheet metal or up to ½ inch steel plate
  • TIG Welds chrome moly tubing or thin steel sheet metal or stainless up to 3/8 inch thick
  • Arc Welds up to ½ inch steel and stainless
  • Welds aluminum up to 1/4 inch with a spool gun (item 20172 sold separately)
  • Holds either 8 or 12 inch wire spools
  • Square Wave Inverter
  • Fully independent MIG and TIG Gas Systems
  • 10 feet long power cord so you can weld anywhere
  • Holds 2 bottles for both MIG and TIG welding
  • All 3 torches are more than 12 feet long
  • Extra long TIG foot pedal (15.9')
  • Includes gas flow meter
  • Side hooks for easy cable storage
  • True DC TIG welder with foot pedal and high frequency start!
  • WP17 TIG Torch included for greater flexibility

Why Do You Need This Multi-Process Welder?

You want a welder that allows you to Stick, MIG and TIG weld. And you're probably interested in this unit because you'll be able to MIG and TIG weld with a single powerful machine. Most multi-process units are basically MIG welders with a scratch start TIG that greatly limits the abilities of the machine. We designed this machine with a true TIG welding function with a high frequency start and foot pedal like you would get from a welder devoted to TIG welding. This will allow you to not only have the ability to do high quality stick and MIG welds, but also TIG welds, and that is why this is the machine for you.

The rated Duty Cycle refers to the amount of welding that can be done within an amount of time. The Eastwood MP250i has a Duty Cycle of 60% at 250 Amps. It is easiest to look at your welding time in blocks of 10 Minutes and the Duty Cycle being a percentage of that 10 Minutes. If welding at 250 Amps with a 60% Duty Cycle, within a 10 Minute block of time you can weld for 6 Minutes with 4 Minutes of cooling for the Welder. If the Duty Cycle is exceeded, the Welder will automatically shut off, however the fan will continue running to cool the internal components. When a safe temperature has been reached, the Welder will automatically switch the Welder output back on. To increase the Duty Cycle you can turn down the Voltage Output control.
