welder for IC piping?

OK, rather than asking what is the best welder out there at a certain price point, I'm going to ask for all the cheapskate idiots out there like me.

I need to weld new intercooler piping, and modify my downpipe, so I'll need a welder that can weld 16ga and 18ga steel.

What is the cheapest machine to get the job done, and would a cheap POS work to butt-weld the pipes together and hold boost?

If you don't mind gobby, ugly, spattered welds, but a non-shielded flux core machine from Harbor freght/Home Depot/etc.

lincon weld pack 100, is cheep and easy makes a decint weld on 115 volt, little practice you can weld that stuff with flux core no prob with minor spat and dog balls, if there is any nothing that a file and emory cloth cant fix.

some advise if you buy one, and weld...DO NOT use an extension cord. you loose lots of amperage and the weld wont penetrate.

step up to 120 or 135 amps for about the same price. Keep in mind, the cheap stuff will have fewer "necessary" features. Case in point: the Hobart migs have 4 voltage settings (not exactly precise) while the Millers have infinite settings but cost $100+ more. Also keep in mind that the cheap HF welders and others will make crappier welds than a decent name brand welder. I guess it all depends on what you want to trade off for a few bucks though.

btw - I've used a Miller Sidekick 90 amp 110v box to weld up 16 ga. pretty well. It had the 4 voltage zones, but it would still make welds "that'll work". All in all it was a decent sh*tty welder, but for my money, I'd definitely pony up the dough for a $5-600 box that will be a lot more precise, versatile and trouble-free

I was at Lowes the other day and they had a Lincoln 180 for under $600. Would something like that be a good welder that won't be "grown out of" too quickly?

yep, that is what I did and have a nice 6" angle grinder too, nobody knows how crappy the welding is once the welds are ground down smooth

the 135 would be the minimum that you would want - the bare minimum. 180 is much preferred and as you found out it is available for little more. 180 would be a bit more versatile - 210 even more so, but the price dfference is much more substantial. In the end it really depends on you - for me, I had my heart set on a Miller 175, as it would handle all my welding needs, until I could get a tig. But with an unstable work-room situation, I NEED something portable and able to be used anywhere (110v), so that's why I'm asking Santa for a Miller 135 this year.

Well it looks like I just got REALLY LUCKY!

I asked my father-in-law about the $389 Hobart 175 on Ebay and he said I could have his "old" welder. it is a MillerMatic 250!

Said something was wrong with it, his workers said it was having problems feeding wire I guess. He replaced the gun and wire feeder but said it still needs some tuning. His accountant talked him into buying another one so the Miller has been sitting in the shop for the past 3 years.

I think that's worth a trip to the repair shop!

How good are you at welding? I would honestly pay someone to do it for u. I have a sh*ttty lincoln with flux core, but I rather wait and use my uncles top of the line welding machines. Some welding machines are so sh*tty , even with a good welder, it still looks like bird sh*t

i hade recentlly bought an auto arc 115 volt. It welds aluminum and steel nicely but it ran me about 2k with all epuiptment. I have a seprate gun for alluminum with plastic sleaveing in it.
It is great for every project and very easy to use

Do you have welding experience?

I have done a lot of welding and from mig to arc to tig, remember that you get what you pay for and the results you want may not come from low $ items. ARC welders are tough for thin material, not that they dont work but they are difficult to use on thin material, TIG is great for thin and MIG IMO is the SHIZ! they are great for thin to thick, well some and if you have a gas attachment you will get great looks and good penetration with little spatter and no air bubbles in the weld!

Or just take your parts to a local exhaust shop and have them do it?

Just get a remanned Hobart or similiar and use that. If you don't have experience welding, expect to ruin a bunch of metal for a while. I would practice on some thicker metal (like 14g) to get a feel for maintaining an arc, etc, then move to the thinner piping used for exhaust/intercooler stuff. Make sure that you have as little gap as possible to fill and only weld 1/4-1/2" at a time and wait until it stops glowing before moving on until you're comfortable enough to run a constant bead. I usually use 0.030" wire for exhaust stuff and 0.023" wire for thicker things.

Anothing thing that is really useful if you're not experienced welding is an autodimming mask. It's a real pain in the ass to learn to weld and use a fully dimmed mask all the time. By the time you're in a good position and find the seam you need to weld, you've usually burned right through it.

Have fun, welding it pretty entertaining.
