I purchased this adaptor as I have a small stock of disposable gas bottles from an older welder and wanted to make use of them for some smaller tasks. The adapters work well and attach easily to the new !80 machine.

The tig function is as yet untried but if it's as good as the stick it's excellent. I don't know many who would use a welder like thus but if I'm asked I'll recommend you guys alone . The fit and finish of the welder and the quality are top notch

it works
16 January 2018
Unable to remove the fitting in my disposable gas bottle regulator valve without risk of damaging it to fit the 1/8 screw threaded adaptor. Therefore ordered another adaptor kit from elsewhere which had 4mm push-on tube type fitting.
