w00t! FINALLY bought gas for my mig and the welds are mucho better I've noticed sometimes a lil smoke by the welds...should I raise the pressure? I've been trying 5-7 l/min. btw, the gas is a argon/co2 mix

 

my new toys: lincoln sp135T and husky air tool kit (might be going back....thinking i should get better stuff...)

The toys:


Some of my first welds. Well, not my FIRST, the the better last ones on my first day....





What'd you think? I know I can improve...but where? This is on 1/8" scrap steel (had to grind the paint off) w/ L-56 .025 wire. Set at D (highest) and about 5 (wire speed).

Few questions? Does it matter if you go left to right or right to left? What am I looking for? Does anyone have a pic of a "perfect" mig weld? Also, how do I weld w/o filling my mask w/ gas and fumes? To get close enough to see good I'm right over the gun...

 

almost looks like you are useing the flux core, are you? dont need to use the gas with that if you are... if that is flux change to soild and then use gas it will look alot better, i think you need to change the + and - on the welder when changing to soild and flux core. iv got the same welder and i made a fullrace style manifold for my crx. works fine, no cracks "yet". good luck

 

its not flux core...


btw, have any pics of your migged tubular manifold?

are you saying that 175 amps isn't enough for 40 schedule?

 

Are you moving the MIG gun with both hands?

Buy the MIG welding video at:

Great video.

welp im returning the weld-pak hd to home depot tomorrow.. and cracking open my new weld-pak 100 hd! regular $325, missing gun, marked down to $125! im seeing these other guns available for 70 or 80 but im just gonna go with the original lincoln magnum 100l for like 110-145$. still keeps the total cost at ~250

 

We are in the market for a MIG welder here also, our old mechanic left and took his with him, so we have to TIG weld everything. It is a pain in the *** in some cases. Im looking at a small unit like a Miller 135 or maybe even 175. However, i might even opt. for the lesser Hobart brand. hmmmm... descisions, descisons...

 

I've used both the Miller 175 and the hobart 175 and I have to say that they are damn near identical and in all actuality I prefer the Hobart(what I have) to the miller that I used to use exclusively. Plus for under $500 you can't complain! great machine!

 

yeah man if you check out the hobart forum you'll see that a lot of people are having issues with the miller 175. You might want to keep an eye out for a lincoln 175. They seem to be slightly ahead of miller and hobart in that category but hobart comes in a close second.

 

Are there any advantages/disadvantages to Oxy-acetylene compared MIG welding? I'm looking to buy a basic welding setup soon and after reading through this thread, I still have no idea which to go with. I'm not really looking for which can be learned more easily, just which can make better welds on a variety of materials. Any help would be appreciated.

with acetylene theres a greater learning curve. you have to regulate the flame as well as the rod. you have to refill the tanks every once in a while. say a 40lb tank lasts about 3-4hrs, and costs about 25bucks. you can braze, weld, and heat things (ie making sheetmetal soft), and also you can cut through just about anything with a cutting tip. thats another thing, you need different tips for different thicknesses. they run about 10-15/each i think. you can find a rig with some tips for about 150used.

go with a mig. never have to fill, easy to learn, easy to use, dont risk heating the entire object just to weld (you can easily tack weld), expandable to weld stainless steel/aluminum.. a decent new lincoln runs about 325. imo its hard to find used ones for cheap.. stick to lincoln/hobart/miller for quality and reliability.

Thanks. Right now I'm looking at a Lincoln SP135T, any opinions on that? I'm just looking to learn how to do some basic welding, eventually I'll have to weld in a transmission mount for my Accord and possibly a downpipe.

 

awesome thread... i love looking at the welds.

heres some aluminum welding on my charge piping... if the pics are too big just tell me and a resize will be in order, i made em kinda big to criticize the welds.






they look alright?

 

i thought i'd finally contribute to the thread cuz i've been playing with my mig welder

 

hehe makes me pumped up to back to welding class after break btw i'm in high school

 

This is a SRT-4 Turbo kit I made for guy in Canada...Someday I'll be famous...or maybe infamous...either way people will know me so it doesn't really matter.






Special thanks to...Matt_sb2000, Gunnar, CAMP 1320, No Limit Motorsports, TiAL Sport, and one Canadian.

Yes it can. Stainless or mild steel wire should work fine.

Here is a pic of a plenum we made from sheet aluminum.

 

Looks tight man. Where the flange that it bolts to the head though, i am i blind is its not done yet ?

 

This plenum fits an australian made car (holden commodore, uses a Nissan 3L six)
the runners come from the bottom of the plenum then bend towards the head.

This pic might make it clearer....

 

Good eye! UPS fucked up and it wont be here til tuesday...kinda busted a nut and took a bunch of pictures. :-P
