Market for my Welder Control Box

admin

I could ask this question somewhere where folks would blow smoke up my butt, but I figure the grizzled veterans of WW will give me a better answer than most anywhere else. In case you have not been following along with my (FASCINATING) adventures, I've created a box that plugs into my welder's pedal connector that gives it a bunch of features that it doesn't come with from the factory:Max-output limitation when using pedal4T operationPulsing, up to about 30 Hz, and possibly as high as 100 HzModified pedal travel/output mappingThe first three features are standard on welders even slightly more high-end than mine, but mine doesn't come with them. The last feature, as far as I know, I invented it, so I'll explain it briefly. What it does is make it so that the first 25% of your pedal's travel takes you up to 75% of your welding output setting. Then the remaining 75% of pedal travel uses the last 25% of your welding output setting. The idea is that you get a lot more sensitivity up near the welding output, where most of your usable amperage is probably going to be anyway.I've been thinking about whether there would be a market for this sort of thing, or whether it's a one-off that only really applies to owners of my specific welder. The thing is, the PA160-STH lists for $489, but if you go even slightly up in price range, you quickly get to welders that come with pulse and 4T operation standard, such as the Power I-TIG 200, which lists for $699--a $210 difference. Are there really very many welders (TIG or stick, since you could have a scratch-start rig and still use the box) that have a pedal or remote socket that don't already have these features? Is there even a market for this?Everlast PA160-STH... and that's about it!
