You are here: Home > MIG Welders > Pro Pulse™ 300
Our flagship Pro Pulse 300 carries on, but also brings to the next level, the legacy of the Pro Pulse 220 MTS. While we designed the Pro Pulse 220 MTS for home or repair shops, we packed the Pro Pulse 300 with even more power and duty-cycle for manufacturing work in an industrial setting. The Pro Pulse 220 MTS and the Pro Pulse 300 share many features, such as the same convenient LCD and easy to understand menu, as well as many of the same accessories, including push/pull guns, spool guns, and remote controls. But the similarities end there.

We cut no corners when we developed the Pro Pulse 300 and packed the power source with even more features than those included with the Pro Pulse 220 MTS. For instance, while you may be familiar with the awesome arc dynamic of the Pro Pulse 220 MTS, the outstanding arc dynamic of the Pro Pulse 300 will absolutely blow you away. Also, on a machine of this magnitude, you expect the best of the best, so
we designed the Pro Pulse 300 to run on single or 3-phase power from 200V to 575V—with no de-rating in output or duty-cycle ever! Additional unique aspects of the Pro Pulse 300 include the hardware and software we use, as well as the accessories and features available on or for the Pro Pulse 300.

Hardware: Only the best! Infineon® IGBT inverters on sophisticated, lacquer-sealed circuit boards—which makes for an IP23 class machine suitable for work in almost any working environment and in most weather conditions. The Pro Pulse 300 also includes two gas solenoid valves, which enables you to keep a spool gun or TIG welding torch, in addition to a MIG welding gun, connected to the machine at all times (though you cannot perform multiple welding processes simultaneously). No gas tanks to switch, no set up to take down. Leave your 30 Lb. spool of wire in the machine, leave your MIG gun attached, press a button on the front panel, twist a plug on the front of the machine, and, as simply as that, you switched your welding mode! Furthermore, a Swiss-made, 4-roller, geared wire feeder, with digital encoder and independent pressure adjustment, ensures the perfect wire feed at all times.

Software: Includes all of the features you can possibly imagine. MIG single pulse, double pulse, manual adjustable double pulse, in ALL programs, with ALL alloys, and on ALL base materials—from steel, to stainless steel, to silicon bronze, to aluminum...everything. The Pro Pulse 300 features hot start and slope down (crater fill) options like you've never seen before. For instance, you can choose either timer controlled hot start or trigger controlled hot start, and you can also choose your hot start intensity. Plus, you can set your slope down time, as well as your base current at the end of slope down, for the perfect termination of every aluminum weld. The Pro Pulse 300 also includes 32 synergic programs to meet all of your fabrication needs.

We thought of everything before we built the Pro Pulse 300, and offer medium and heavy-duty air- and water-cooled MIG welding guns, air- and water-cooled push/pull guns, air- and water-cooled spool guns, smart, on-demand water-coolers that detect problems with water flow and fluid levels and turn the welding output on your Pro Pulse 300 off to protect your water-cooled torches and guns, fully adjustable pulse stick, fully adjustable pulse DC TIG...the list goes on an on.

A relatively lightweight package (the power source alone weighs 95 Lbs.) makes the Pro Pulse 300 portable enough to bring to any job site. You can run the Pro Pulse 300 on a 12000 watt (or better) generator, or plug the Pro Pulse 300 into the wall no matter what power is available.

No matter what you weld, from the thinnest auto body material to the thickest, multi-pass material in an industrial or manufacturing setting, the Pro Pulse 300 is the right machine for you. With programs to meet almost every need, from dual shield stainless to pulse aluminum on a variety of alloys (4043, 5356, 5554), the Pro Pulse 300 handles every job meeting or exceeding your expectations! We offer over-the-phone or in-person, at our shop, assistance to train your welders in the setup and operation of the Pro Pulse 300. For a fee, we will also set up the Pro Pulse 300 in your shop and train your people to unlock the full potential of the Pro Pulse 300. Many of our commercial customers appreciate this service.

Starts at $4,895.00* (Price for the Power Source Alone; Accessories Sold Separately)
