The 24 Series (240A) gun for welding steel and the 26 Series gun for welding aluminum are both out of stock. You can still place your order online but your order will not ship until we receive new gun inventory.

We expect to receive new gun inventory around the end of January 2021.

The Pro Pulse™ 220 MTS—a multi-process machine capable of MIG, synergic MIG, synergic pulsed MIG, DC TIG, and Stick—offers a manual mode as well as 22 synergic programs, both with and without pulse, giving you the advantage of a virtually spatter free weld! Parameter selection on pulsed process welders can be complex, but the Pro Pulse 220 MTS features synergic technology, making parameter selection more intuitive and automatic. In fact, the Pro Pulse 220 MTS, with its three-step process, makes setup a breeze and gets you welding in minutes—simply select your process, wire diameter, and material thickness during automated setup. The 8 square inch LCD featured on the Pro Pulse 220 MTS adds to setup simplicity by telling you which gas your application requires; the LCD also enables you to easily view and adjust your weld parameters.

The Pro Pulse 220 MTS also offers ST-arc. The ST-arc function reads welding parameters back to the welding machine live (while welding), and monitors and keeps the arc length constant, while allowing the stick-out (contact tip to work distance) to vary. ST-arc, essentially, allows the new welder to focus on the location of the weld, as well as the travel speed, and also allows the experienced welder to keep a perfectly uniform bead and uniform heat input, which enables the welder to achieve good welds in tight corners—a feat that couldn't be reached previously with conventional welding equipment.

The Pro Pulse 220 MTS also allows you to set and store up to 30 different weld jobs, and with the Trigger Job function, you can apply three of the 30 different weld jobs to the welding gun trigger—simply depress the trigger to call up each job. Essentially, with the Pro Pulse 220 MTS, you get multiple, highly specialized MIG welders in one compact and light-weight package. And with the addition of a TIG welding torch and remote control, the versatile Pro Pulse 220 MTS also functions as a lift-arc, DC TIG welder.

Here at HTP, we pre-programmed the Pro Pulse 220 MTS with 22 synergic programs (both pulse and non-pulse) and one classic, fully manual program, each geared toward welding applications using mild steel, aluminum, stainless steel, silicon bronze, or flux-cored wires.

Pulse welding on mild steel gives you excellent penetration, due to the extremely hot spray arc, and also gives you perfect puddle control for both in- and out-of-position welding. Remarkably, the Pro Pulse 220 MTS, when used on clean material, provides a virtually spatter free weld—from start to finish—which results in a very smooth bead appearance, with no need for cleanup.

You can also weld aluminum with or without pulse. Our advanced, synergic programs and the Swiss-made wire feed assembly featured on the Pro Pulse 220 MTS enable you to feed aluminum wire with repeatable precision through our standard MIG welding gun. The ability to maintain a stable and smooth arc at 22 amps allows you to weld aluminum as thin as 1/32" (0.031"). Our pre-programmed Double Pulse program allows you to make "MIG like TIG" welds with the desired "stack of dimes" look. And for all welders who are in a hurry and never have time to preheat aluminum, the Pro Pulse 220 MTS features a built-in hot start function, which lets you set a predetermined amount of time that you weld at a hotter setting before switching back to your standard setting. We also incorporated a crater fill function for aluminum welding, which minimizes crater cracks in your welds. Since 4043 and 5356 aluminum alloys feed and weld differently, the Pro Pulse 220 MTS comes set up with programs for both.

In addition to mild steel and aluminum, we also included programs that allow you to pulse weld stainless steel. Again, pulse welding stainless steel provides nearly spatter free welding. We also included the option to adjust pre- and post-flow gas, as well as slope down for MIG, which allows your stainless welds to turn out "like TIG".

And for those who weld galvanized steel or sheet metal, we included a silicon bronze program that allows you to weld silicon bronze with a pulsed spray arc. A pulsed spray arc enables you to weld galvanized steel or sheet metal without melting the zinc coating or without distorting the sheet metal. Lastly, we included gas-less flux-cored programs, as well as gas shielded flux-cored programs for your structural welding and fabrication needs. A simple polarity reversal on the front of the machine allows you to weld using flux-cored wire without shielding gas. You also want to reverse polarity for TIG welding.

A light-weight design makes the Pro Pulse 220 MTS the ideal MIG for use both in the workshop and on the job site, and the multi-process nature of the machine offers nearly endless possibilities when welding.
