You're on your farm.
A piece of critical equipment is broken.
You don't have a $3,000 mobile welder on the farm.
You don't have a high current outlet for a shop welder anywhere near the equipment.
You can't easily move the equipment to your shop.
Time to try to get a commercial welder with mobile equipment to come over?
Not if you have the ZENA™ mobile welding system installed on your tractor, truck, or other farm vehicle -- or on a small motor/engine.
Just drive to the job. Connect welding/control cables to the power generator. Start the engine & set it to a fast idle. Start welding. Finish welding.
Fast. Easy. Convenient.

can be installed into virtually any vehicle (tractors, ATV's, trucks, emergency vehicles, forklifts, construction equipment, water craft, lawn tractors/mowers, etc.), transforming it into a self-contained mobile welder with performance and operating features that equal, or exceed, heavy and expensive transportable engine-driven industrial welders.

Built to meet or exceed military and underground mining equipment specifications, all ZENA welders are ultra-compact, producing more power for a given size without sacrificing reliability or performance in any way. Compact sizing also makes installation/conversion relatively easy.

A unique patented solid-state control system allows the operator to precisely and instantly control welding current -- without the need to stop welding -- from fingertip controls built into our electrode holder. There is no need to vary engine speed to control welding power, nor does the operator have to go back and forth between the vehicle and the work site to make adjustments to the equipment

For operator safety, power IS NOT supplied to the electrode holder UNLESS the operator depresses and holds a push-button safety control. Don't try changing welding rods and/or welding while standing in a pool of water with any other stick welder. It can be very uncomfortable and very unsafe -- with the ZENA system, it's a snap!

Welder output is also ELECTRICALLY ISOLATED from both the vehicle in which it is installed and earth ground. Weld safely in reverse or standard polarity without any chance of damage to delicate electrical components.

Usually the ZENA mobile welding system is installed to work with a vehicle's existing electrical system. However, the ZENA power generating unit can replace the vehicle's existing alternator. Operating (when not welding) as a high current power source that outperforms any stock alternator.

Improved Welding Characteristics

ZENA welders produce a high frequency DC output in both standard and reverse polarity modes which produces an extraordinarily fine bead and a welding joint with better appearance and less impurities than other DC stick welders.

Further, when compared with the welding performance of other DC welders, the ZENA mobile welding system provides greatly increased welding efficiency (arc temperature and penetration).

Simply stated, a 150 amp output from the ZENA system is functionally equivalent to 180 amps, or more, from an ordinary welder!

Take a look at this short video showing a 150 amp ZENA welder stick welding.

Mobile Welder Models for Every Application

All ZENA welders are rated for 100% duty cycle operation.

Models range from our popular 150 amp welder (the perfect choice if you typically use 1/8” rods and do not need to use rods larger than 5/32”), to our 200 amp welder (3/32" to 3/16" rods), to our 250 amp model -- and on to 300 amp to over 1200 amp multi generator welders. All models are available for use with existing 12 or 24V electrical systems and (when welding) use from 1/4 to a maximum of 6 amps of electrical power.

Larger models produce sufficient power for heavy duty welding jobs, including air gouging. However, the larger models may not fit into small vehicles, but will fit into larger tractors, loaders, and trucks (3/4 ton+).

All ZENA welders are compatible with all types of AC or DC welding rods.

All ZENA welding power generators can replace an existing vehicle alternator (or function as a booster/quick charger) when retrofitted with an external voltage regulator.

High quality 20 foot long welding cables are standard equipment on all models, and longer length cables (from 30 to over 200 feet) are available on a custom order basis.

ZENA welding power generators can also provide power for MIG and TIG welding applications.

Hydraulic & PTO Drive Welders

We make unique self-contained welding systems, designed for special applications:

Our hydraulic drive welders are perfect for use on modern service vehicles, farm, and construction equipment. Models include second generation systems designed specifically for retrofit to man lifts and other specialty vehicles used in the incredibly harsh conditions suffered by rental equipment and on-site construction. These second generation hydraulic welders require no routine maintenance whatsoever and have a design service life longer than that of the equipment in which they are installed. A service life so long that we expect them to be refitted to new equipment rather than retired with the equipment to which they are originally installed.

And our factory-built PTO drive welders can be used on any farm tractor with a standard 3-point hitch and 540 RPM PTO.

Do-it-yourself PTO welders (CLICK HERE to read/download simple instructions) are also VERY easy to build -- using parts available at your local farm supply store.


Want to automatically control vehicle engine speed and conserve fuel when not welding? Easy to install throttle control devices are available which have been designed to work perfectly with your welder's controls. Push the “power” button on your welding handle and your engine speeds up to a fast idle for welding -- when you let the button up, the engine drops back to an idle.
