I have been hanging the torches on a holder on the table, so if anyone ever stepped on the pedal by accident, it could only arc to the holder/table, which is attached to the ground clamp. Not sure it would even do that though, given the tungsten is pretty far from any metal. That's not the case with the product pictures. We haven't had any accidental arcs yet, but arcing to the bottle just seemed like a bad idea. I'll take a look at the cart. The bottle isn't insulated from it. The welder and cart are on the opposite side of the welding curtains right now, but maybe I'll insulate the bottle anyway. Thanks for the idea.
Todd,
I'm no expert, but I will say this. The ground goes from the machine to the work, or as many do and I do, the table. There is actually no way for the tungsten to arc on the bottle if it's on the cart, even if it was touching metal, because the cart should never be grounded to the clamp, but let's say you mistakenly clamped the ground to the valve or something like that, that could potentially be a problem. In this case I don't see how the tungsten would arc to the bottle even if it was grounded, the tungsten is isolated from the bottle entirely with the way the holder is setup. That also goes for the magnetic holder I use on my table, it keeps the tungsten away from the table so in the case as you point out, someone steps on the pedal. My pedal is under my table, so I have to physically be sitting with my foot on it.
EDIT: I just realized that if the cart was touching the metal table, and the bottle wasn't insulated, and the live torch while the pedal is pushed is close to the bottle, there could be a chance of arcing the bottle. I think the paint could possibly be an insulator. And also if pigs could fly...
Now let's say the bottle was stored on a mobile welding table, that could present more issues as the work/table is grounded to the machine, so there would be more chance to arc the bottle than if it's stored on the cart itself.
I should add, in this picture you commented on, the torch is not even connected to the welder, it's just a 2nd torch being stored on the hook.
