what you think of my weld on spintech custom muffler?

[Ls2cam]

*I welded on it first time with MM252*

I set up the different voltage/wire speed to test which i welded.
1) Voltage and Wire Feed Speed-
15.9/133
15.8/120
15.0/140
15.8/140 is best choice I used.
2) Run-in speed (run) 120%
3) Preflow (PrE) .2
4) Postflow(POS) off
5) Burnback (Bur) off
6) Spot Timer (SPO) off
7) Stitch Timer (dLY) off
8) Gas 25%/75%AR mix.






any correction??

Why would you put that ugly muffler on your new welder

[cruizer]

Yeah, I'm with monte, I wouldn't be showing those pics to anyone, cause the welds are horible, and I wouldn't be scratching up my new machine

[Art.]

Putting that nasty lookin thing on top of a brand new miller is just wrong. You should have taken the money you spent on that machine and paid for some weldind lessons.

any correction??

Next time I would turn on the shielding gas.

Reminds me of the guy with a porsche, but no driver's license.

COME On...any help??? I don't need to hear any harsh words..

The machine looks fine and no scratched.

Thank for reading this post.

I would say first learn how to appreciate your equipment and then learn how to weld. A lot of guys here would love to have your welder and wouldn't abuse it right off the bat. I wonder how you will treat it later and then come on the forum asking why it it doesn't work. That's just me. You can do as you please. I wish you well.

Looks like your attempting to weld Stainless with mild steel, either that or you have the wrong type or no shielding gas

[bayweld]

First off, you are trying to do something and trying to learn and I commend you for that...you have made several mistakes judging by the looks of the welds and the smoke stains around them...It looks like that muffler is made from stainless steel??(check with a magnet, good stainless is not magnetic) and It is hard to tell what the pipe you welded on to the muffler is made of...Perhaps aluminized steel? If you want to weld stainless you will need stainless wire and a gas suitable for the task...Argon/co2 is not suitable for stainless...Ask your supplier about a tri mix gas...or get a recommendation here.....
I hope this helps...Tell us what the muffler and pipe are made from and what type wire you are using....What are you going to put the muffler on? Good Luck..

This has got to be a joke, but since you asked you might want to order millers weld handbook its only $40. I don't think I would call that a weld.

Looks like they come in either Aluminized Steel or Stainless

If you have the Aluminized steel then you'll need to grind that coating off and expose the Steel to be able to get any decent bead.

SS requires SS wire and a Tri Mix gas

Ls2cam,

Hey man. I'm with Bayweld. I think it's great you are making an attempt at welding! I don't use my machines for a tool chest, workbench or tabletop, but that is your business.


Hiding there in the "harsh" words is some constructive criticism from bayweld and cruizer. I think you need to evaluate what metals you are welding, choose the appropriate filler wire/shielding gas, and get some help on how to "lay down a basic GMAW (gas metal arc welding) bead. You can get a lot of practice in, but practicing the "right" way is important.

It is doubtful you will find information on the very, very, very basics of any welding process on this forum. Do you know anyone close to your area that may give you some quick pointers and "hands on" lessons with the basics? Judging from you pictures I truly believe you need "hands on" training. Learn the correct way and practice 'til you can do it right. I don't have the means to make you a video or I would gladly do so.

By the way: "you ain't seen no harsh words" from any of us. Those are reserved for the really ****'d up ****.

I commend you for trying. You just need the desire to learn (I think you have it), some "hands on" training, and lots of practice. You already have a !!!KICK ASSZ WELDER!!!my friend!!!

Good Luck

Ls2cam,

down19992000 has excellent advice. Take it.

Good Luck

go to your local scrap yard and get some material to practice on. most yards will sell you scrap at scrap price, so its alot less money to get some material to practice on. Then find someone willing to give you some hands on. reading books and forums will only get you an idea of what you need to do. If you dont know anyone that can weld find a welder and ask him to teach you for a couple bucks. cheaper than school and youll probably get better info out him.

cant really say what your problems were with that muffler, but it is definetly a combination of many things.

but good luck with the learning.
