Searching ebay, I found this:
As the seller says:
"Brand new arc starter with a patent pending design which will add high frequency and arc stabilization to any welder. The entire driver module, transformer, spark gap, and capacitor assembly is only 2" by 4" for incredibly easy installation. The installation and hook-up of the unit has been greatly simplified. The yellow wires are for 120/240VAC input power. The two blue wires are for your tig switch. You will not find an easier or more inexpensive way to add high frequency to an existing welder. Also included in the kit is a filter assembly to protect your welder from the high frequency power.
The patent pending driver cube (only 1"X1") has a zero crossing detector included in the design. It turns on the high frequency portion of the circuit when the arc is about to extinguish. Without an arc stabilizer, as the AC waveform approaches zero, your welding arc will go out. There is nothing to keep the arc going as the voltage has dropped to zero. This happens 120 times a second on 60Hz power. On European 50Hz power it happens 100 times a second. Lack of an arc stabilizer can lead to poor weld quality, especially when welding aluminum. The patent pending driver of this unit turns on and superimposes high frequency onto the weld current to keep the arc active so it won't ever extinguish. Other systems from major manufacturers, which I won't name, either only have the high frequency at the peak of the AC waveform (when it's not needed) or randomly generated with no phase locking to the input waveform. This is a main reason why previous systems could not match the performance of a square wave AC welder. With our phase locked zero crossing high frequency generator, the performance is similar to welding machines costing several thousands of dollars. Ask yourself, why would the largest welding companies make a product which would cause they multi-thousand dollar welders to be useless? Their HF add-on units are designed to be faulty on purpose. A competitor company which manufactures a cylindrical arc starter has their HF at the peak of the waveform. This may be fine for arc starting but useless for the arc stabilization required for welding aluminum.
The driver cube and high voltage transformers are encapsulated in black epoxy. For the transformer, the reason is simple. The black epoxy adds protection from corona and sparking which can occur with any high voltage system. The driver cube, being patent pending, is encapsulated so it doesn't end up on a Chinese assembly line. The black epoxy also completely protects the circuitry from vibration and environmental exposure. The driver cube also contains an isolated power supply and opto-isolated switch for user safety. The driver is activated by only microamperes of current so your tig switch should last almost indefinitely.
With your purchase you will receive a complete driver board which includes the driver cube, high voltage transformer (also 1"X1"), tungsten spark gap, class 1 dielectric 30 kilovolt 1000pf low dissipation capacitor, and all necessary wiring already installed. You will also receive a 400 amp coupling coil which can be used at 60% duty cycle at the rated current (100% duty cycle at 200A). The coupling coil is hooked to the driver board by push on connectors which are already installed. You will also receive with your kit a dual acting active filter to keep the high frequency from interfering with your welder. Also included are panel connectors for your tig torch. You will also receive an installation manual and any customer support you can imagine. I designed and built this kit so I know it better than anyone. It really is only a two part kit, a driver board and coupling coil. That's all there is to it.
All of this for under $100 which includes shipping. Who says America can't be competitive? This entire system is designed and assembled in our shop in Memphis. No need to go out and spend thousands on a new welder when you can simply add this system to your current unit. 100% money back guarantee. Buy with confidence and upgrade your old stick welder to a tig. Now you can weld aluminum with your old transformer welder. "

So, has anybody tried this or a similar device? Either as adding HF start, or as arc stabilizer ?
Any ideas welcome.
