It's a big bracket to hold an oil pump on a truck.
1/4" 1018 steel
200 amps, 3/32 red tungsten and 3/32 filler.
I was rather impressed with myself. Did 10 total

My third time at welding aluminum. I don't think it turned out too bad considering it was welded with an Arc welder, a separate Freq box and a "Clip on" TIG setup :) I also weld stainless, but I don't have any pictures of anything since it is all from work... maybe one day I will get a pic.
 
Hey guys, I hope I don't catch flack for this but this thread is pretty much my welding info resource. Im looking for a little guidance here. Over the past several months I've been piecing together a tig setup for hobby use. I really don't know much about tig at all except what I've read and seen here. I've had a good bit of experience with mig because I used to work in a bodyshop, but zero stick or tig. I'd like to go to school and learn how to weld properly, but i'm a full time college student working in the oil field full time also so I literally have no time to go to school and learn. I was really hoping you guys could help me determine what else I would need for my setup. A friend has been "obtaining" various welding supplies for me when he works shutdowns so I have what I believe to be a good bit of the materials I need already. This is a list of what all I have so far....

Along with those items I have a Maxstar 150stl and a pipeliner helmet. My question is what else will I need? I know I need tungsten and gas, but what gas should I get and should I BUY a bottle or rent one? What size bottle would I need for hobby work like messing around with manifolds, exhaust, and pretty much anything else that's just small non-structural work? Thanks for your input!

^You would want a 100% Argon gas for tig welding. I would recommend not anything smaller than 80 cubic feet bottle, which lasts about 2 hours of continious welding and even that runs out pretty quick if you are doing a big project. I bought mine at AirGas on exhange basis, i think the really big 250 cf bottles could be rented though.

Looks like you have just about everything needed to get started, just get some 1/8" mild steel plates to start running beads on. Worry about all other accessories after you get started in welding, for now just worry about starting an arc and running a bead while not burning through the metal. :)


Did this dice recently, gave it to my dad as a small gift.

Also, tried welding some rust. Dam thing ate all my electrode and boogered up my cup. :-(

Dude, did you buy the dice off ebay? i plasma cut these and threw a few on there.
 
Well, that's what the guy at airgas told me, either way it runs out fast when doing a project and i'm not even talking about if you're practicing and trying to stack beads on a plate. If i didn't have a cage in my car, i would've definitely had a bigger tank.

The best tungsten imo are 2% Thoriated (Radioactive), 2% Lanthanate, and 2% Ceriated but check with your welder. Sometimes different welding machines work better with certain tungsten, also depending on polarity. The ones mentioned above are good all around.

Gamble, i'm pretty sure those dice plates came from you. You must have not seen my note when i purchased it. :p
 
There are some seriously talented welders in here! I may have missed throughout the last 92 pages I just scanned through, but has anyone built an aluminum exhaust yet? Pictures?
 
Didn't see the note. Want more?

Proven fact. Air gas employees pretend to know but they are clueless.

Polarity on tig doesn't change. DCEN for everything. Decp to ball up if you want. That's it. Generally
 
Picked me up a little lathe

Looks like the chuck jaw or whatever it's called is giving me issues. Anyone know of a budget friendly upgrade? One that can hold something larger and 3 or 4 jaw? I know 4 is for grabbing square, but is better to use a 4 as all in one solution?
 
Look up Msc direct. A 3 jaw chuck with reversible teeth will allow you to hold larger items along with pipe. An independent 4 jaw chuck would be nice for odd shaped pieces or turning offset pieces. Check for play on the slides and adjust if needed before you go to town on it.
 
finally bought some more argon and had some time away from work to practice my aluminum some more.
Longevity 200sx
3/32nd gold tungsten
15cfh on the argon

I was grinding the tungsten with too much of a taper so once I read a little more and reground it things started looking much better. Keeping the puddle without burning through on thinner tubing is an issue for me so I am not gonna bother with tubing anymore until get the hang of everything on some 1/8" stuff. Doing the pause in equal increments is a pain in the ass since my hands develop Parkinson's as soon as I pick up the torch.

My gloves are toast and my LWS doesn't have anything but extra large. 2 weeks until new gloves arrive.
 
I picked an internship kind of thing at a race car building shop, the experience is amazing. I've got to weld mainly chromoly and steel. One was a very intricate rear end on a pro-mod type car.

I just finished a tubular k member for a mustang! Might sound like nothing to you guys but I'm stoked and it's great experience.

I dont normally take pics of mig welds but we had a shop owner stop by and was amazed at my welds on the cobra chassis so i thought i might aswell get some pics for my records. Made him want one he said haha

Im still not 100% on this but ive come along way in just 1 year. This is now my 2nd year at this place and in welding all together so i am progressing.

Picked up a small JET bandsaw recently, and though the base and bow are well built from cast iron, the cheap gauge metal legs were definitely an afterthought on JET's part. Lay a 24 ft stick of square tube on it and the legs would buckle and the saw would drop. Additionally, the saw sat an awkwardly low height.

86ed the included garbage, and fabbed a new one from some 7 gauge stainless 2x2 and 3x2 tubing. Allthread adjustable legs from McMaster. It is a heavy son of a bi***, but adds much stability.
