## Overview

The ZENA® Model MW200.40 is a powerful 200 amp DC engine-driven welder kit designed for versatility and ease of use. Manufactured in the USA, this compact system can be attached to any 16 hp or larger engine, allowing for mobile welding capabilities that rival industrial-grade machines. With a 100% duty cycle and a unique remote control system, it offers instant adjustments without interrupting your workflow. Ideal for commercial duty and outdoor applications, this welder is built to last and comes with 40' cables for maximum reach.

## Description

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/engine to which it is installed and earth ground. -- This allows the owner to weld safely in reverse or standard polarity without any chance of damage to delicate electrical components on their vehicle OR equipment which is being worked on. -- Usually the ZENA welding system is installed to work with a vehicle's/engine's existing electrical system drawing power from the engine starting battery and alternator. -- However, with an optional voltage regulator module, 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.

## Features

- The ZENA MW200.40 mobile welding system is MANUFACTURED IN THE USA, by ZENA, Incorporated, and is designed to be attached to, and driven by, any 16 hp, or larger, electric start gas engine (or equivalent motor) -- OR installed into/fitted to virtually any engine driven vehicle -- 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.
- We've been building these (for more than 20 years now) to meet or exceed military, marine, 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. -- And we provide great documention, built in diagnostics, and a real person (in and from the USA) to speak with you if necessary M-F 9-5 CST.
- Our unique, patented, electronic remote control system allows the operator to precisely, AND INSTANTLY, control welding current 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 welder and the work site to make adjustments to the equipment, -- and, WELDING CURRENT CAN BE ADJUSTED WHILE WELDING -- WITHOUT THE NEED TO STOP FOR ADJUSTMENT.
- 40' electrode holder and ground clamp cables are included in this package. -- Longer cables are also available. - And, if desired, optional panel mount controls that allow the owner to use their own cables are also avilable.
- The MW200.40 is designed for BIDIRECTIONAL ROTATION applications (viewed from pulley end).

## Questions & Answers

**Q: can it couple direct to the shaft of the engine?**
A: Not unless the engine is one that is rotating at a speed of 7000 rpm while producing about 12 hp (if a gas engine) or 7 hp (if a diesel).  To our knowledge no such engines are currently manufactured.
The units are designed for belt drive where the necessary speed differential between drive engine and driven generating unit can be easily resolved by using different sized pulleys.
Such as drive mechanism is also MUCH more inexpensive than a direct drive coupling system that can handle he necessary torque, surging load, and speed.
