I know it’s a necro thread, but I just bought one and had a few minutes to play with it last night.
WOW!
My first finger control was a Miller East/West knob, and it totally sucked! I was never able to use it for anything more than an on off switch, and a simple momentary button would have been much easier.
That’s what drove me in 2004 to buy my SSC pedal, which I still love to this day.
But the pedal is not great in all positions, and I have a job coming up that requires being on the floor, so I went looking for something better, which led me to the SSC Touch 4. It’s a fraction of the price of the alternatives (TIG Button and CK Steady Grip), and looked more rugged as well.
To make a long story short, it has exceeded every one of my expectations. To the point that I just ordered a new air cooled torch to go with it, since I think I may be using this more often now (the pedal will remain connected with my water cooled torch). And my hardly used Miller RCCS-14 is going on eBay as soon as I have the time to list it.
It’s not replacing my pedal, but if I didn’t have a pedal already, it probably could. The four levels work just fine for me, and I see no need for a continuous range of power. They really got everything about it just right.
