I havent tried it yet myself. Just been to cold and to many Christmas cookies to eat inside. I have the flux core in there now so I will give it a try and then switch back to solid. The cheap used welder seems to have the gas flow messed up. When I hooked it up I read tank pressure ok but the regulator side wants to stay about max. I took it apart and there was some crud under the bonnet I cleaned it out but I think the diaphragm is bad. It looks like a part you should be able to replace but Im reading on the welding forums no one fixes them any more. Its reading high so I guess that wouldnt hurt but I will use up my gas quicker. It reads out in cubic feet per hour so thats a pretty small flow rate. I have seen people on line also using a restriction flow valve or a fitting with a needle valve to slow the flow way back. Not sure what thats all about. If I have to buy a new gage setup I will.
For now Im sticking to mild steel only maybe if I get halfway proficient and buy a new better machine I might look for a spool gun for aluminum setup also.
Right now I have solid and flux core all .035 and only .035 tips. As for gas I see there are two types one is tapered on the end the other straight. All the gas nozzles I have are the tapered ones and the one that came with it is all curded with spatter from flux core. I assume the straight one is for flux as it doesnt do anything except protect the tip.
How about the tip dip jelly stuff in a can? Do you use that?
