Re: Fit Up Help on Trailer Coupler Replacement
With a tight gap at the top and getting increasingly wide as you go down - I generally weld where it fits, then hammer the gap closed while hot.

Re: Cutting 1/4 5052 aluminum
I use a jig saw on aluminum with a wood blade running fast. I also use chop saw and circular saw on it. For your inside cuts, I'd likely use the circular saw for large plunge cuts, then finish with the jig saw. I've cut many feet of 1/4" steel sheet with my skilsaw and a metal cutting blade. Wo...

Re: Trying to learn (thin sheet metal)
I can't see the images - but you are not going to get really nice body panel results with flux core. Just go ahead and use solid wire and gas. I use 100% co2 to save money. I rarely use mixed gas. Here is my '89 f150 plow truck I saved (and sold to my brother). All welding was with 0.035" wire ...

Re: Welding heavy steel
It's a 300 amp machine, that's why only a 300 amp rating. The plugs I use are only rated for 50amps, but I was pretty tempted to swap in a bigger breaker anyways. The power mig 300 is rated at 60% at 300 amps. But its max is 350 amps. Don't worry much about the plugs. They hold way more than 50 amp...

Re: Welding heavy steel
Back plug welds are done, started a couple of the fillets. So far I've managed to trip the 50 amp breaker 6 times. I guess that's why people use 3phase wiring on bigger machines. I wouldn't worry about 3 phase, your breaker is just too small. That machine lists 62 amps input at 300 amps. I didn't s...

Re: Extreme porosity in second pass
Did you clean the oil out of the interior of the pipe?
Sort of looks like galvanized pipe, but you said it wasn't so that's not it.
Btw, when cleaning out the oil, do not use chlorinated brake clean spray. The fumes from any remaining liquid can be transformed into phosgene gas when welded.

Re: Best way to TIG this weldment
If I read your drawing correctly, that's a really awful joint configuration to weld. Any chance of a gradual flattening of the round tube to make it easier to weld? Plus, the side-to-side rigidity of that configuration is quite poor (rocking motion). The welds are close together and result in the tu...

Re: 6010 Root
Since 6010 is easy to run vertical down, I use it whenever the gap is wide, or the material is thin, or I'm in an uncomfortable spot and just need to sew the joint closed before using 7018.
Those are some of my criteria for fixing something. Easy way to get the job done well.

Re: Building up a steel pin by brazing or O/A welding
Because you have a lathe, I figure you must have proper measuring tools.
Measure the holes, see if bolts are the right size, or standard pins.
If not, I would buy material and machine to desired tolerance.
Practice on the pins anyway - then toss in the scrap barrel.

Just an fyi, some welders can get damaged by jump starting.
As a result, charging the battery, then starting it, is a better practice.

Re: Not again - more dirty deeds
I've done several cast aluminum repairs like this one.
Just be sure to clean it with a die grinder, only use enough power to puddle it, weld it up
Just welding and grinding to shape works too.
Either way, a good file finishes it off nice and straight after rough grinding.

Re: Pushing the welding parameters of the amperage.
Yes, won't be a problem. Around 180 amps would be fine for steel, and stainless uses less amps.
