Multi-Purpose Units |
|
Multiprocess also known as Multi-Purpose Welders, Multi-Function Welders or Combo Welders are becoming ever popular in today’s welding industry because of the portability and availability to have all your welding and cutting needs met from one single machine. LONGEVITY MultiProcess welders feature TIG/STICK/PLASMA CUTTER combinations from small sized machines ranging in weight from 40-70lbs and no bigger than the size of a standard microwave. Our WeldAll Series combo welder can generally weld and cut all types of metals including aluminum, steel, bronze, copper, stainless steel, mild steel, etc... With our WeldMax series Multi Function Welder, you will be able to cut and weld all metals except aluminum. Choosing the right welder is made easy with this resource page.

More MultiProcess Welders Information
With multi-purpose welders you will be able to easily switch from plasma cutting to TIG Welding to Stick/ARC welding in the matter of seconds as each LONGEVITY unit comes with easy setup features. As far as quality, the Combination Welders come with a variety of power capabilities, amperage variations, and welding capabilities ranging with units that can weld all types of steel including aluminum – please make sure you select a unit that has AC/DC TIG capabilities for aluminum welding. You do not need an ACDC welder to cut aluminum only to weld it. With a LONGEVITY Multi Function Welder, you will never be out of the right tool for the job and you are not sacrificing space on your truck or in your shop. Longevity Combo Welders are portable, reliable, and powerful to meet most welding professional or hobbyist needs at a very affordable price tag. You are not sacrificing quality from a multi purpose unit vs. a stand alone unit because Longevity engineered a way to combine plasma cutters, TIG/STICK welders into one machine by combining each technology featured in a stand alone unit. Therefore, by having separate circuits for each TIG/PLASMA/STICK function we are still maintaining high quality and not over working the motherboards or capacitors in one combination small sized welder.
Please browse our multi process welders and let us know if you have any questions, |
