HW200 -- Rear/Pulley Side View -- Grill Open 22"W x 12-1/2"H x 11-1/2"D -- 1.8 cu. ft. Taking up less than 2-1/2 cubic feet of space, and requiring as little as 8-10 gpm of hydraulic system flow @ 1,500 psi (with optional low volume motor upgrade), six different standard models are available -- 150A, 200A, 300A, 400A, single operator 300A/dual operator 150A, and single operator 400A/dual operator 200A. (Other system control options are also available.) Custom/OEM units, vehicle body built-in kits, and do-it-yourself assembly models are also available ALL models are 100% duty cycle. Our hydraulic welders are based on our patent pending welding technology and utilize the same unique control system as all of our other mobile welding products. All models include electronic switching circuits which can be used to control hydraulic system operation and/or vehicle engine speed. That's not all! All models can also be used with ZENA's Universal MIG Spool Feeder Adapter or our Universal MIG Spool Gun Adapter -- allowing you to add MIG welding capability to your rig. These hydraulic drive welding systems can also work with ZENA's custom built TIG power adapters.

Bolt the welder into place (don't worry about exposure to the elements). Connect, to the welder's drive motor, a flow controlled, overpressure protected 3/4" hydraulic inlet/supply line, and an unrestricted 1" outlet/return line. Connect one wire to your vehicle's chassis ground and another to a low-current (10A) ignition switched 12 volt (or 24volt) power source. That's all there is to it. When your ready to use your hydraulic welder, just plug the 20 foot long welding/control cables into quick disconnect connectors located on the welder's weather proof/maintenance free aluminum enclosure, and you're ready to go. All that's left if to start your engine, set the engine speed (if not using ZENA's built-in speed control circuits), and activate any necessary hydraulic valves (also not necessary if you are using automatic controls). That's it! You're ready to weld! Call 615-897-2011 now to discuss your specific application.   FARMERS --- also check out our PTO drive welders.
