Thats the one i have (135 from Lincoln) and it was the best one i could find that used the 120, although i didnt really look anywhere other then lowes.. haha

its not as powerful as i want but it does the job when i weld with 304L or 308 stainless steel wire .30 size i think it doesnt penetrate as much as id like/should but with the steel wire like .25 it does good. i always use the thing at (D) the highest setting and speed 3-3.5 and it works good. i made a manifold for my t3/t4 using the ss 304L 90's sch 40 that everyone else uses and it worked fine. so id give it a if you cant use a 220</TD></TR></TABLE>

would you happen to know if those tig welders are any good?

 

I think the tank is 20. It's just now starting to run low on pressure, I've been using it for a long long time, hard to make a guess on the hours but it should do fine for ya. It's a CO2/Argon mix. When I bought the machine it came with some fluxcore, I used all of that up and decided to buy all of the gas (the machine was gas ready) so I hooked up the tank, the lines, and switched the polarity and welding with the gas compared to flux core was night and day difference.

People use flux core when they're welding out side if there's wind, since the wind can blow away the shield gas. I think flux core might have better penetration, but I'm not sure. But you definitely want gas, if you look at the pic, by the red gas can, you see some welds which have some brown/white **** around them, that's from the fluxcore.

Hey sporkcrx,

thanks for the reply again....so a 20cf tanks is good huh? well, ill go look around for a welder that has gas capabilities. I see some wire feed welders that are cheap, and im soo tempted to buy them.
For example, I saw this one on Ebay.. http://cgi.ebay.com/ws/eBayISA...&rd=1 seem like its has the capability of connecting a gas tank. Is this brand good? How much would someone pay for this?

I cant see the picture clearly, would you be able to take close up pictures of a comparison of a flux core weld VS a gas sheild weld? Oh, do you by any chance have a website that sells the same type of welder you have?

thank you again..

 

remember when buying a used tank that if its not certified within 10(?) years i think, you gotta pay a fee when exchanging it. i had to pay an extra 25 per tank i think cuz mine were outdated at 1989 or something.

 

I know I could use some classes and all but I'm just showing these off for some imput from the pros who know at autozone.....oops i mean you guys. again, I'm just starting, about an hour under my belt so far and starting to understand the concepts and rhythm needed for tigging. Anyone that hasn't tried tigging, it's definately more fun than mig! and from what I've grasped so far, not as difficult as I thought it would be.
flame away!

 

That first bead looks like you're rocking the pedal and applying too much heat and/or not dipping fast enough.

What are your machine's settings?

What kind of material?

Type/thickness of filler rod?

Argon flow?

Tungsten size?

sonny

 

sorry to ***** this thread,but I thought maybe people in here are looking for a nice used machine or 2.

chekc out my thread, I need these out of my garage

https://honda-tech.com/zerothread?id=760055

 

dont be afraid to dip that filler rod in like a madman.

 

ooww the pretty colors.

 

Miller synchrowave 180
power on 70
some 14 ga stainless scrap stuff
filler say ER 70s-2 1/16"
argon is on about 25
not sure on the tungsten, i got a bunch free with the machine, no details on it though

so, just a bunch more filler rod huh, not as much rocking of the pedal.

 

General rule of thumb = 1 amp per .001" of wall thickness. Looks to me like you're not dipping fast enough. I run my argon at around 15 cfh. When I'm welding steel, I don't rock the pedal much (if at all). Here's one of my more recent purty welds:



Your weld bead looks like this: ooooooo
Try to make it look more like this ccccccc

Sonny

 

right on, thanks for the tips sonny. i like the little o's and c's that's neato. lol
so you're keeping it full pedal and just dabbing after you pass and get a puddle. I'll turn the gas way down too. I'll get some more practice tomorrow and see if I can get some improved beads going now that I have some pointers.

 

I've got some questions for you guys now. What about welding Cast iron. I have heard mig is a problem, and i am most likely just going to braze. Any suggestions? i have to repair a cracked exhaust mani

 

Tig it all the way. use nickel filler rod, and pre-heat the manifold to 200-300 degrees before welding.

also try to grind a "V" groove where there are cracks to increase hte penetration, and drill out the ends of the crack so it cannot continue to crack.

 

tig isn't an option. I am deciding between mig and oxy/acetalyne (sp?). the reason i am repairing it is because someone already welded the flanges to cast with a mig welder, causing some cracks. i think i am gonna braze the cracks, it seems like the best method to me.

niiiice ghetto garage bro..

 

It's all your crap now

 

best method is tig.. all the way, brazing will just cause it to crack again unless you use nickel, really....

 

hello,

would anybody have a close up picture of a weld that compares flux core VS gas mig weld?

thanks....

 

they will look almost identical if its a good welder, as in person welding. gas is more convenient because of no clean up.

 

what do you mean by clean up??? would it be possible if you can elaborate on that? Oh also, other people said something about flux splattering..what does that mean too?

Thank you and much appriciated...

thats the clean up he means.

 

gonna post my brazing of a cast iron manifold later tonight, we'll see how she holds

Ohhhh. So when using flux core wire you need to clean up the splatters then? Does anybody have a picture of what a splatter looks like? is it like little small ***** on the welds that looks like bubbles? How do you clean something like that? just a wire brush?

And also, does a normal (gasless) welder be able to weld stainless steel, and other types of steel? can aluminum be welded too?

Thanks again for the replies....im just checking to see what my opions are, cuz my parents might not like it that I have a gas tank in the garage..hehe, but who knows..

thanks!

 

when flux core splaters, its usually cuz your not using gas.. (oxy/argon mix). when not using gas, and doing it that way, you get really shitty, messy welds.. still penetrate, but not like a nice clean mig weld.

i dont' have any pics.. but really, you want a complete break down, maybe do a google search, and learn the different types of welding.

i doubt the mod's at HT ever though we'de be teaching welding classes. heh
