With gas I was basically unable to weld with this (and the bottles were expensive). Would only deposit some bird droppings on the surface. Converted to gasless and it is now great for 'rough' jobs. Currently working on the floor of my car which is thoroughly treated with Fluid Film which is hard or impossible to get rid of. So popcorn welds but they seem strong. I bought a couple universal torch sets thinking to use one but as a post here showed me they are incompatible (had found out it did not work) - the button wiring is different. Then the plastic liner broke and I decided to use the steel lining from one temu set. Success, it fit pretty well length wise and i was able to use the brass nut from the temu set to fasten the liner at the feeder (had to file a little to get it through the hole). The original brass piece/nut does not fit he steel liner. The 'temu' liner is strong, wider than the original but fits well and feeds better. The welder is still hard to control. For some reason it only feeds when set on High voltage setting, otherwise only clicks. Still good for rough/casual jobs. I guess others have used such a liner, seems recommendable. For me here in Norway it was a cheap method too, these torch sets were cheap, under 15 euros. It made sense just adding them to a temu order with free postage. I see people use curtain wire, I could get that here but with postage it would not be cheaper and I could not find it in a shop nearby. The sets are compatible with my Azzuno 160 new Chinese welder so will just keep the parts.
