Not really. It was because he preferred to step into his LWS and buy everything he needed there. That was what they could do for him to make his system work with what they had on hand without ordering and waiting for parts or fittings. I have a 256, and I havent seen a torch yet that I couldnt hook up to my machine if needed. I ordered a single barbed gas connector that fits our machines and I interchange it with different torches. You just need to make sure you get the dinse 50 connector. That being said, I have an air cooled torch with a dinse 25 connector, so I just stuck the end of the 25 into a 50 off an old SMAW stinger. Works just like it's supposed to.
