So apparently the part I thought was missing from the oxycon is not a necessary part. I've been worrying for nothing. It would only be necessary if I were using the oxycon in a medical situation. Since I'm not, it's all good. Now just need to get DH to attach the hoses to the new torch & I'm in business. I tried to do it myself, but just don't have the strength to do it myself. Hopefully Sunday I'll be able to give it a try.
