Without modern welding techniques, cars, skyscrapers, fixed-wing aircraft and trains would not be possible. And as welding equipment continues to evolve with advancing functionality, powerful welding tools become increasingly accessible. Among the most functional of these tools are multi-process welders, which for many operators, can be a real gamechanger.
What is a multi-process welder, and when do you use it? A multi-process welder is a welding machine that is capable of performing multiple types of welding processes. Multi-process welding machines are designed for scenarios where welding equipment must adapt to ever-changing job needs, including differing base metals, varying workpiece thicknesses and specialized welding joint types.
Multi-process welders make it easy for welding operators to tackle a variety of fabrication or construction jobs and projects on the jobsite, in the shop or in the field without switching power sources, helping to save you time and money.
Praxair provides welding equipment and accessories from the most popular manufacturers, as well as our own ProStar line of products. Our ProStar AVENGER 140 MP MIG Welder is a portable, direct current (DC) inverter wire feed welder capable of welding steel or stainless steel with solid wire (with shielding gas) or with flux core wire, using the provided MIG gun. It also comes ready to accept an optional spool gun for welding aluminum. This machine also has smooth DC stick capabilities and the ability to perform lift start DC gas tungsten arc (TIG) welding on steel and stainless steel materials with the optional TIG torch.
This ProStar AVENGER 140 MP MIG Welder is capable of MIG welding 3/16 inches carbon steel in a single pass. It uses leading edge inverter technology to provide high-quality welds that are crisp, clean, consistent and strong enough to impress the most experienced welders. One of the many advantages of inverter technology is its ability to create more welding power from a smaller transformer.
The AVENGER 140MP also provides for stick welding with electrodes up to 3/32 inches with the exceptionally smooth DC stick welding output on materials such as steel, stainless steel, cast iron, hard facing, and aluminum. Typical applications include construction, auto repair, farm and ranch and light industries.
