I'm confused.... Are you talking about oxy welding with a torch? Or cutting with one?
That's one thing I dont have is a set is an oxy/act setup.
That's why I got the multifunction machine with the plasma cutter.
The 3.5 shade is the clear shade, the "dark" shade is adjustable from 9-14 Iirc.
I have it set ~10-11 right now since I've been doing only tig stuff ~50-150amps or so, when I try to stick I will turn it up more to 12-13 or so.
Any of you guys welded up any aluminum intercooler piping?
If so, have some general settings that you don't mind sharing?
I'm hoping to get enough practice in to be able to do cams (ted95s') intercooler piping for him here in a couple weeks.
I will be doing his exhaust piping for him, iirc he bought stainless for that, along with an electric cutout like Dustin (batman722) has.

If I gave you some dimensions, could you make me a bracket in Aluminum? I don't know exactly what I need yet but I could make you a template in paperboard and mail you it :rofl:

Sure.

Awesome, I'm trying to figure out how to mount this trans cooler....I think I'm going to need 1/2 of a square, but I'm not sure yet till I have the bumper off again to eyeball and measure some things and make the template. Guessing that this would use about 2-3 feet of 1/8th AL stock (maybe 90deg for rigidity) with about 2-3 welds on it could you rough guess a cost? I know, probably impossible. I figure this would probably take about an hour from start to finish with a piss break.

meh, dont worry about cost, as long as its nothing crazy, ill throw it together for ya.

Sweet!

got more practice in today, another hr or so, starting to get a little more consistant and co-ordinated with both hands, i think once i get some extra cash to either build a welding table, or at least get one of those portable "nomad" welding table like jody uses, it will really help, right now im welding on a wood topped bench thats way to high for me, with a peice of 3/8" steel laying on top that i use as a ground point/heat sink
so settings are as follows:
3/16" aluminum diamond plate (welding on the backside)
3/32" 2% thoriated tungsten, ground to a dull point
3/23" 4043 filler rod
160amps max footpedal controlled
a/c frequency @ ~125
a/c balance @ ~ 40%
a few pics:
the first is the overall pratice, the last couple are my best bead so far.
got a little hot there right at the beginning, started working the pedal back a little late.
still need some work filling that crater there at the end, i gotta work on putting in that little bit of extra filler as i work the pedal more.
getting there!!

What are u cleaning the metal with prior to welding?

Using a stainless brush and a wipe with acetone after

one brush per metal type! using the same brush on steel, ss, al will contaminate.

Yup. It's a stainless brush, that I use only on aluminum.

Use a SS brush on everything

yup, diffrent stainless brush for each material.

been practicing here and there, when i have time, last night i decided that i was sick of just running beads, so i hacked up a few peices of 6061-T6 aluminum (1/8") and fabbed up this thing....not really sure what it is...calling it a tool holder..i can stick it under the hood and throw my wrenches and crap in there while i work..lol unless someone can come up with a better use...jenn said it kinda looks like an arm rest...guess it kinda does..lol

~99 amps
3/32 4043 filler
3/32 yellow tungsten
a/c freq. ~ 100
a/c bal. ~ 40
on to the pics!







think im just about ready to actually start building stuff now! haha

definitely, that looks perfect Manny, amazing learning curve.

Nice man. welding its its own art form and when you get it down you be able to custom fabricate almost anything and it'll last. i know who i'm gonna ask for custom fabricated stuff

thanks guys, definetly have some plans to bring some stuff to the 6gc crew, just need some time and money to get started getting the materials.

Looks good. Your stops/starts are pretty good too(my worst area for some reason)

yea, i learned from watching jody on www.weldingtipsandtricks.com to kinda feed a little bit extra filler at the end, right as you start to ramp down and back off. its definetly getting better the more i practice.

I miss Tig welding, but it wasn't offered this semester. I need to get my hands on one!
