The Welding Thread

red2.4srt that is awesome!

Did you see much distortion post cooling?

Just ordered a 480v Mig welder for work a couple weeks ago, can't wait to break it in! I was just talking to the on sight rep for the Company that owns our operation, told him how the gas stick welder was great for outside, but not ideal indoors. He agreed, and told me to pick something out but keep it under $3500 and it wouldn't have to go before the board.

Fuck yea.

Damn red lookin good!!!
Next time use a folding banquet table to weld on brother. Welding on your knees gets old......or I'm getting old!

Thanks guys, i'll be trying to start the wood portion here soon. I have lots of square cut nails to get out of the 2x's before I can glue them together.

I did notice some twist in the frame, but nothing too crazy. I'll be capping the bottoms of the tubes off with 1/8" plate. I'm going to drill the center of the plate and weld a nut on the back side of each cap so I can put on some threaded adjustable feet. Hopefully it'll all work to plan!

Is anyone here still using a torch to weld? I just picked up a rig so I can cut and heat stubborn parts, but it came with welding tips as well. I've been experimenting but still don't really know what I'm doing in the least.

I've seen it done once, old wrench was a artist with it.

Never attempted myself.

I did.. 20 years ago. lol

jealous of the welds. I get to design this shit all day and never get to do any of it. I wonder if my buddy still has his Lincoln welder.. he spent a lot of money on it and I don't think he ever used it. I need to weld some brackets to my car for motor mounts. hrm..

It's a lost art, I need to pull my rig out and play with it again. Puddle follows the heat, and unlike traditional welding (tig/mig) you don't want to melt the base metal. braising is more like.....gluing with a glue gun rather than full fusion. you want the piece nice and hot, and use the flame to melt the rod.

Hope that didn't confuse you more.

It has been years since I have used Oxy/Ace to weld or braze. I do know it does take quite a bit of practice, it is a lot like TIG welding. (similar motor skills) Works well on thin material. The first exercise we did in class was to run bead after bead after bead on some 1/8" sheet with no filler rod.

I think the liner is toast on my mig. I don't know how old it is, but I bought it used 3-4 years ago, and it hasn't really welded anything quite right in a while.

My Eastwood MIG 135 performed great when doing some trailer repairs yesterday. Just an FYI.

What do you have? Liners are fairly cheap in the grand scheme of things, I usually sell them in the store for $15-$20. They're quite easy to replace as well, worst case you can remove yours to inspect it for any kinks or crud.

Can't wait to break this in! 60% duty cycle at 200amps, up to 1/2" steel. It will be nice to have a good Mig in the shop.



Also built the back board here using 7018 stick a couple weeks ago. I literally come up with ideas to build shit just to keep practicing. All of our equipment is so new I don't have to do much reapir requiring weld, so I find other ways to improve the muscle memory.

^ That miller looks pretty nice.

I have a little lincoln Mig Pak 10. It was setup for flux core when I got it, and I've run maybe 2 baby spools of ER70S-6 through it, a spool of the old flux core crap, and like 1/4 baby spool of ER308L. I'll probably pull the liner sometime soon, but I don't really have any plans to weld until the spring, so I'll probably put it off until the last minute.

Did you change the polarity when you switched from FC to 70S-6? All of Lincoln's smaller MIG's come setup for FC from the factory and thus are set to electrode negative (ground hooked to + terminal on the welder). They weld like shit if you switch to solid wire and don't change the polarity to electrode positive (ground hooked to - terminal on welder).

The liner you'll need is just a standard Tweco style 35-40-15 liner for .030-.035 wire. We sell them for $9.xx IIRC?

Started making a setup to more easily pull e30 drive trains. Future plans have wheels, and a way to hold the engine/trans separate for easy splitting/joining with the engine.
