Rodcrafter, I did think of that, so I figured if it did start that, I would just tack the tubing together to keep it from moving, then take it out of the the clamp and finish off the weld. Don't know if slag will splatter or not, would not bet against it with my newbie welding skills, lol.
I've had parts shift from just tacking in place. Additionally the heat sometimes causes warping or movement. Then, I'm solidly out of square wondering what the heck happened!
Make no mistake, there ain't no powder in this Puff ! And... I'm not really a crazy person but I play one in real life
Oh I bet they could Puff, the clamp should keep the tubing tight and not let it move, to allow them to be tacked into place or welded together fully. Hopefully you don't heat it up so much that it does warp, will see, anything that will be an extra hand for me and help me along will be nice.
