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. 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 . Improved Welding Characteristics ZENA welders produce a very high frequency pulsating DC output in both standard and reverse polarity modes and produces an extraordinarily fine bead and a welding joint with better appearance and less impurities than other DC stick welders.
Larger models produce sufficient power for heavy duty welding jobs, including air gouging.
