commercial-duty, engine-driven, 100% duty, portable DC arc welder in the world!

Best of all, a ZENA mobile DC welder can be attached to the engine of ANY existing vehicle (saving the cost of a separate/new engine). This unique welder is equally at home on:

Forget the old stereotype of needing a huge engine driven welding machine taking up most of the space in a pickup truck bed (and most of the payload as well) to do commercial welding. Our new technology allows us to replace these behemoths with generator packages so small, and weighing so little, that there is no practical reduction in vehicle payload -- and absolutely no loss of vehicle cargo space! Though, you will notice a huge reduction in your welding equipment cost!

And, thanks to fingertip remote controls that let you adjust power even WHILE you're welding, you'll enjoy far more control of the welding process than you've ever had with any other welder!

Install a ZENA underhood welding system and your vehicle becomes an:


Attach or retrofit a ZENA onboard welder to a free standing engine and you can have the ultimate portable welder:

Installation is simple -- designed for do-it-yourselfers. ALL Parts are modular, wires are color coded, and everything plugs together easily. We even have factory made, bolt in bracket kits for most of the American trucks made during the last 20 years!

Best of all, when you're done, you'll have a brand new commercial duty ZENA welder -- for far less than a worn out used portable welder!

That's right, LESS than the cost of a piece-of-junk welder selling at auction!

And, from one-half to one-fifth the cost of a comparable new engine driven welder!

We have a number of dealers and/or distributors, in the US and Europe who built high quality turnkey, ready-to-go, light weight gas and diesel engine driven multiprocess welders -- even combination service truck workstations providing high amp DC welding current for stick, MIG, and TIG welding; AC power for tools; high current battery charging; and compressed air!
Call us for more information.

And, of course, there's our ultra compact, ultra light weight, super transportable Backpak welder! The smallest and lightest commercial duty welder in the world!


Or, how about a self contained Hydraulic Drive Welder designed specifically for retrofit to service trucks, lift trucks, drilling rigs, and man lifts -- including scissor lifts, boom lifts, basket lifts, cranes, etc.

Forget about having to equip your truck, lift, or drilling rig with expensive, space wasting, heavy engine driven welders, long cables, loss of lift capacity -- or needing a helper just to adjust power and move the welder around the lift's work area.

Specifically designed for the rigors of rental and long term construction site duty -- in all weather conditions. In addition to incredible ZENA welder performance, ZENA's unique hydraulically driven welders offer the ultimate in reliability, ease of retrofit and serviceability. In fact these hydraulic drive welding units require no routine maintenance of any kind!

Best of all, you don't have to purchase a new lift to get an onboard welder! Your existing equipment can be easily converted in your service shop by your own maintenance personnel!


Making Conventional Engine Driven Welders Obsolete -- A Disruptive Technology

ZENA's patented welding power generation and control technology is a sea change -- a true "disruptive technology" in an industry heretofore dominated by a few big firms who have maintained engine driven welder technology with little, or no, real innovative improvement for more than 50 years.

For example, in addition to being relatively inexpensive to manufacture (with NO need to sacrifice quality to make them affordable), ZENA's welders are incredibly compact when compared to previous technology. Yet they are able to produce far more welding power than old fashioned, engine driven welders more than 5 to 20 times their weight!

Better still, these tiny powerhouses produce remarkably little waste heat and ALL electronic components are MODULAR and COMPLETELY WATERPROOF -- sealed in a high tech plastic. And, since heat and moisture are the main enemy of all electronic products, less heat and/or moisture = longer service life (and fewer problems)!

Put another way, these tiny ZENA welders will work productively, and more reliably, for much, much longer than old technology engine driven welders.

This is not just rhetoric Check out our warranty -- 3 full years -- as long, or longer, than that provided for ANY welders made anywhere in the world. And when have your ever seen a welder sold with a 60 day satisfaction guarantee?

And, thanks to built-in troubleshooting features and modular components, there is no need to ever take a user serviceable ZENA welder in to a service facility -- and pay a huge fee just to see if there was anything wrong in the first place. Just follow a simple troubleshooting procedure, observe the action of a few lights, make a simple resistance or voltage reading and you're done.


Small size has many other benefits:

  • Easier installation,
  • lower manufacturing and shipping costs,
  • virtually no loss of vehicle payload capacity,
  • improved vehicle fuel efficiency (less air pollution, etc.)

Equally unique, ZENA's patented electronic controls add a host of features and capabilities that set the ZENA welders far apart from today's host of existing technology based engine driven welders.

See below, OR CLICK HERE FOR MORE INFORMATION.


Last, but far from least, ZENA's new technology welders weld better, and are easier to use, than other engine driven welders:

We're not talking about subtle differences either -- you will notice

  • much better penetration for a given current setting;
  • better arc characteristics;
  • cleaner, x-ray quality joints;
  • easier out of position welding;
  • better out of position weld joints; and
  • unprecedented user control of the welding process.


Choose the 100% duty cycle welder that meets your needs

Our unique modular power generating technology and electronic controls let you mount multiple independently controlled 150A or 200A 100% duty cycle welders to a single engine --- or combine and synchronize multiple welding power generators to create a single giant power generator producing 800 amps (or more) of welding power.

And, with accessories, your welder can also function as: (more on accessories and models below)

All welding controls are built into the electrode holderFingertip Welding Controls

That's not all! Our patented cutting-edge technology puts ALL welding controls at your fingertips -- they're built into the electrode holder! You can even adjust power while welding! Giving you total and instantaneous control of the welding process.

The ZENA welding system features unique (patents pending) welding power generating technology that allows you to make x-ray quality welds, and an electronic control system with a user interface unlike that of any other welder in the world. So good that it will spoil you!

Our controls make welding easier for the novice and yet offer the experienced user unparalleled control of the welding process (particularly when working out of position). These unique controls also incorporate significant safety features which are particularly important when operating in difficult environmental conditions.

However, all the technology in the world means nothing if it doesn't work. Our welders work -- really work! In conditions where conventional welders can't. There's simply nothing like them!

Professionals who have tried ZENA welders (and many were skeptical at first) unanimously report excellent welding characteristics and a very pleasant "feel" -- and both pros and amateurs agree that they are very, very easy to use.

Our half-price flat-rate rebuilding policy further protects your investment. It's simple, we will completely rebuild (or replace) any welder or welder component that we manufacture (including the power generator), anytime, for one-half the cost of a new unit! Even if your pet elephant steps on it -- you're protected!


Reliability is Built In

Built to meet or exceed military and underground mining equipment specifications with sealed / waterproof electronic controls, no other welder better meets the unique maintenance requirements of marine, agricultural, and industrial users as well as others who need access to superior, high-power welding equipment that can be used for repair work anywhere.

Thanks to our cutting-edge technology, all ZENA welders, from our popular 150 amp model to our monster 800+ amp systems, are ultra-compact, producing more power, with less waste heat, for a given generator size, without sacrificing reliability, or performance, in any way.

Compact sizing also makes installation/conversion relatively easy.


If we don't have just what you need, custom systems can be configured to meet special needs and/or OEM requirements. (see what we did for Genie Industries)

Selected FAQ excerpts/notes:

NOTE: Similar engine driven welders are made by Miller, Lincoln, Hobart, Century, Esab, HTP, Mitsubishi, Thermal Arc, and other companies. When comparing specifications, you will find that our 150A unit is comparable to, and will do the same job as, for example, a Miller 225 Bobcat welder, a Hobart 250A welder, a Century 200A welder, or a Lincoln Ranger 8 welder. Of course, 160A, 175A, 180A, 275A, or even 300A, or 400A welders would be also in the same category. MIG and TIG torches made by companies like Miller, Lincoln, HTP, Hobart, Tweco, Ready Welder, and Forney are also compatible with our welders -- when used with the proper adapter.

NOTE 2: Do not confuse our patented welding systems with other underhood welders such as those made by Premiere Power, Mobi-Weld, Stellarc, Ready Welder, and others -- our welders are built from the ground up to weld and feature specifications which conform perfectly to international standards for arc welders -- make a careful comparison.
