making a brutus 10 build and having some trouble with the welds for the gas lines. a friend of mine and I built it and he did the welds but upon testing them all of the welds for the back "gas" pipe and the couplers that got welded in all leak.
How hard is it to make air tight welds? Any thoughts on this would be appreciated.
I don't think it is that hard. The welds shown are kind of standing on top of the metal. Not enough heat and or wire speed for good penetration. the grey colored welds also look porous= tiny little holes=sometimes caused by the gun tip not held close enought to the weld=little shielding gas. Welding straight lines on a stand is a lot easier than going around a circle.
Take it to a shop and get the gas pipe welds fixed by a pro. A TIG torch could easily melt those low heat welds into gas tight beads. Running another wire feed bead over that one is likely to be a disaster.
Thx for the replies. I know this is possible as I've seen it done successfully but was just curious if anyone had similar issues.
Used my compressor and soapy water to test everything so safety was and is a priority obviously
I used pipe hangers, drilled and tapped the holes on the backside of my stand and just bolted them down. I made my stand out of 2x2 steel 3/16" thick so I could drill and tap into it and have enough material to give me enough threads.
