but that's going to stop now. Yesterday I bought a Lincoil Percision Tig 185 from a local dealer. I've only been playing around with it for a little bit so far and at first it was very confusing but I think I'm getting the hang of it now :) :banana: I've only been able to weld steel so far because I don't have the right tungsten to weld aluminum yet. Here is my last weld I did on a scrap piece of pipe. Not bad for only having it for 1 day so far and maybe 1 hour of practice at the most

Looks like your depostition rate looks good, just gotta try to keep the puddle size consistent. Weld up some pipes and steel stock and try breaking your welds, a good way to figure out whether you are doing it right.
 
Matt, my dad has a Cebora 130 MIG that I've used before, but this TIG is completly different to use.

John, I planned on doing that once I found some little scrap pieces of steel. I looked on the inside of that weld in the pic and the penetration is good
 
Nice, thats a good skill to learn.

I need to go on a spending spree. I need ford racing 4.30 gears, a 3" X pipe, a die grinder to open up my tiny bbk longtube collector and i'd like to do a 31 spline rear/posi unit. I want double adjustable upper control arms as well to set the pinion angle.

You can get a Die Grinder for under $20.

Good Luck with that Zach...Wish I could do it!

Thanks Rob! The electric one is $29.99. Home depot/Lowes are in that area and some are a little more. I might head there this weekend and pick one up. Another tool to add to the box :cool: Then I can order the 3" X pipe.
 
:lol: glad to know that... Now I know what to stay away from. Wish my v-band flanges would come in allready so I can get this turbo stuff finished up. I'm anxious to use this thing on other stuff than scrap metal

explain the diffrences of tig and mig. I have a mig, and was told i "can" weld aluminum? So, what exactly is better about a tig?
MIG - Metal Inert Gas welding (aka GMAW - Gas Metal Arc Welding). A true MIG welder has a sheilding gas tank and a wirefeed. Wirefeed welders that use a flux core wire are not technically MIG. If you have the right attachment for a MIG you can weld aluminum.

TIG - Tungsten Inert Gas welding (aka GTAW - Gas Tungsten Arc Welding). This is similar to gas welding because the torch with the Tungsten electrode is only there to create an arc that is the heat source. You feed a wire filler rod in with the other hand (TIG welding w/o filler rod is often referred to as "sanitary").

MIG is good for production (don't have to keep grabbing more filler rod) and TIG is good more for precision and the ability to weld a wide variety of metals.

The difference in the welder that determines if it can weld steel and aluminum is whether your output can be switched between DC (direct current) and AC (alternating current). Steel is welded with DC and aluminum is welded with AC (and you can adjust the frequence along with the current).

Aluminum is far trickier to weld than steel for two reasons. The first is that aluminum doesn't change color when it heats up to its melting point. When you weld steel you can see it turn that orange-red when it's getting hot and about to melt. Aluminum just looks like aluminum and then it's a puddle. The second trick is that materials have a HAZ (heat affected zone) when they are welded and the material properties changed based on how the heat changed the crystal structure of the metal. Steel keeps most of it's strength when it's welded compared to aluminum that gets "softer" in the HAZ and may require heat treatment and induced age hardening to regain the strength of the pre-welded components.

Sorry for geeking out, but that's what happens when you ask a Mechanical Engineer these kinds of questions. :rolleyes:
 
good to see you finally got the TIG you wanted.. Now have fun with it and make some shi*!

BTW, you can use the red tungsten for steel and aluminum. Same goes for the gas. You will of course need 4130 filler rod and some aluminum scrap. Just switch it over to AC and go to town.

And maybe you can give me some pointers of the welder when you figure it out.. I've never messed with any of the settings, other then amperage and post flow.
