hello everybody

is it ok to use arc welders like these to make manifolds? (am i gonna look like a rookie?)

and i would also like to know what are the pros and cons for arc welders?

thanx everybody
best regards

I consider an Arc welder to be a stick welder, which would not be my first choice. but its up to you. you can grind down the welds and smooth them out. hell if it works go with it, but i would practice on some scrap tubes first.

 

Do you know how to stick weld? If you're buying the welder just to get a cheap manifold out of it just buy a used manifold.

If you've never welded before I wouldn't be trying to stick weld pipe in tight corners as your first project. Best bet if you're just learning is to get a flux-cored machine, that way you only have to worry about arc length and gun angle. Stick welding you'd also have to learn to feed it.

 

i pretty much know how to but i need a bit more practice.

wtf is flux-cored?

 

let me explain you....

i know what's an arc welder. ( stick )

i think i know what is mig ( wire and gas )

as far as i know tig is also wire and gas so what is the difference?

 

Gas Metal Arc Welding (GMAW) is frequently referred to as MIG welding. MIG welding is a commonly used high deposition rate welding process. Wire is continuously fed from a spool

Gas Tungsten Arc Welding (GTAW) is frequently referred to as TIG welding. In TIG welding an arc is formed between a nonconsumable tungsten electrode and the metal being welded. Gas is fed through the torch to shield the electrode and molten weld pool. If filler wire is used, it is added to the weld pool separately

Flux Cored Arc Welding (FCAW) is frequently referred to as flux cored weldingSelf shielding flux cored arc welding wires are available or gas shielded welding wires may be used. Flux cored welding is generally more forgiving than MIG welding.

Shielded Metal Arc Welding (SMAW) is frequently referred to as stick or covered electrode welding. Stick welding is among the most widely used welding processes.
The flux covering the electrode melts during welding. This forms the gas and slag to shield the arc and molten weld pool. The slag must be chipped off the weld bead after welding. The flux also provides a method of adding scavengers, deoxidizers, and alloying elements to the weld metal.

try searching on google i did a five second search and copied all this cause im too damn lazy to type it all out.

 

i personally dont like stick welding, but if you want to make a manifold, tack it together with a Flux Core welder and give it to a pro to have it miged or tiged. I personally have a flux core welder it's what i learned on, it's a good little machine

 

I also learned on a flux welder that i still have. I also have a 250 amp ac/dc arc setup that can use stick, and it also has a high frequency box for tig welding. You could stick weld a mani, but it would look nasty unless you have been stick welding for the last 20 years and are very good at it.

dont exaggerate

lets say that the welds are pretty good, is it ok to shave the welds a bit with a disc ? (manifold speaking)


anybody have a arc welded mani pics?

and thanx again for your answers.

 

dont ignore my previous message^^^

but what do you think about the lincoln SP-100 for making manifolds ?

 

It is definitely not the reccomended method, as you will either not get full penetration, or you will have slag on the inside of the pipe....which can easily come off later down the road and kill your turbo.

If you're determined to do it and it's all you have to work with, use very little bevel and make a special effort to NOT burn through to the inside. Use no gap!!

And...don't be surprised if it does crack. But hey...you don't have much to lose, right? If it cracks, weld it back up. And don't expect it to look all that good.
