Radiant heat and the S45 torch

[KHK]

Not sure how the result may be, but how about taking some brake tubing or brass tubing and making a round ring an inch up the handle for those occasions when you are using the machine on thick stock and drilling small orfices to spray cooling air down at the torch where it does not interfere with cutting and see if that helps, or even perhaps two flatten tubes, flared and pointed at the copper contact base to see if it resolve the cooling problem.If it doesnt perhaps a torch with ceramic nozzles.

I havent seen a ceramic nozzle for a S45 torch. The 200pi will not work with a different torch.

isnt that machine rated at 1inch cut capacity, i would think it should do 9/16 pretty easy.

You are correct, 1 in capacity. The problem was the radiant heat generated from cutting such a thick piece of metal, in a small area, and then diong the same cut about 6 in firther down the angle. I don't think I could have done the cuts with a hand held torch, I would have cooked my hands & arms. A few of the cutouts were red hot when they fell from the main angle iron.

could you make some sort of aluminum collar to use as a heat sink?

Yes there are plenty of solutions. The purpose of the post was to inform everyone about the limitations of CNC and the S45 torch..
