Soldering with power generated by this ET Hydrogen dual-torch hydrogen welding system is a terrific alternative to using pressurized fuel and oxygen tanks in your shop—and a dual-torch system allows you to have two operators working at the same time, to run two different torch tips, saving the time of changing back and forth as you work, or to get extra power when needed using one torch. This state-of-the-art system, designed to meet a full range of jewelers' needs, is extremely safe and easy to use and lights with a simple push-pull shut-off mechanism. Its flame is very dry (no condensation of water vapor) with no sputtering. The torch handle is light and maneuverable—ideal for fine work and long work sessions. Visual controls keep you aware of the solution levels and power levels as you work and allow you to set the power you need for any given soldering, welding and brazing task. With a flame that adjusts to precision fineness, this system handles even the more delicate repair and design work. All of this in a system that is highly space-conscious—its footprint takes up a minimum of precious shop space, making it ideal for any shop, anywhere.

This system produces energy by electrolyzing hydrogen and oxygen atoms from an electrolyte solution, creating a safer, cleaner, more economical hydrogen/oxygen fuel. The fuel gas produced by this catalytic reaction is highly effective with the added benefit of being a clean-burning fuel with zero CO(2) emissions, no oxidation and no condensation. Both the electrolyte solution and the necessary flux solution are mixed as needed by the operator. The electrolyte solution lasts you for as long as a year before needing to be refilled; the flux solution is also mixed as needed but needs refilling more often, approximately every 6–8 hours of soldering time at maximum power. Mix the electrolyte (500220) with demineralized water, following the instructions included with the electrolyte. Mix flux (500222) with methyl alcohol (700003), following the instructions included with the flux.

This system requires very little maintenance and what maintenance is needed is extremely easy to understand and implement using the support materials available. We highly recommend an annual performance tune-up with the maintenance kit (500255) available for this machine.
