Which Welder For Me?

Hi everyone,

I have been arc welding for about 3 months now and would like to think I am fairly good.
I have also done a little bit of oxy-acetaline torch welding.

It is now time for me to buy my own cheap welder .
I will be using the welder to weld exhaust piping, charge piping (intake), and eventually make an exhaust manifold.
The toughest metal I will be welding will probably be 304 or 316, 10 gauge SS.

Here are the cheap welders I am considering:
1. http://www.harborfreight.com/cpi/cta...emnumber=91811 - TIG
(will gas be expensive?)
2. http://www.harborfreight.com/cpi/cta...emnumber=44567 - MIG
3. http://www.harborfreight.com/cpi/cta...temnumber=6098 - MIG
4. http://www.harborfreight.com/cpi/cta...temnumber=6271 - MIG

Thanks,
Alex

I'm no expert.
I think the only thing you can weld with a flex mig welder is steel. not SS

I would go with the mig that uses gas or that TIG/stick.
A stick welder is ready to go with out gas. more convenient and harder to learn.
If your good with a stick welder go with the TIG/stick.
Do you have 220 volt power for the welders.

What I don't like about some of the low end migs, maybe its was first ones made, the wire feed units were junk.
Look at some feed units on different welders.
I paid about $28 for C25 gas to fill a 3 foot tall tank (50 cubic feet) for mig welding.

Yup those would all make nice boat anchors. How thick of metal will you be welding? This welder would be ALOT better than those cheap units.

I'm also looking into DIY welding for custom turbo + exhaust.

I think I'll be only doing charge pipes + exhaust, and I'll get manifold done by professional. Let me know how your effort works out.

The thickest piping I will probably be welding is exhaust piping.
Dont know the exact thickness, but its obviously not very thick.

As of now, I will probably buy this one:
http://www.harborfreight.com/cpi/cta...temnumber=6271
I dont want to spend more than $200

I would buy a arch welder but from my experience, stick welding on a round surface is practically impossible. 90% of my welding will be on round things.

For the material you will be welding, a MIG is the way to go. Stick is fine for heavier metals but it is nearly impossible to get the heat low enough to do thin metals.
Have to comment on the welding of "round" surfaces. I have been a pipe welder for 30 years and its ALL round. LOL.

You never got any of the square schedule 40 boiler pipe?


On a serious note, dont buy those pice of junk harbor freight, clarke, etc welders. They are cheap for a reason, you are far better off buying a quality unit OR checking if you can rent one and lining up all the jobs in a weekend.

You stick weld all your pipes?
I think your 30 years give you a slight edge over me

Notes.

$ About-maybe.
Regulator +$65.00
50 cubic ft bottle $109.00
C 25 gas $28.00
hose for regulator + $5.00

Talk to a welding supply house about the way they exchange the bottles
when you want a refill they take your new bottle and give you an old bottle.

Post # 3 shows a Hobart welder with the regulator.

Some migs use (optional kit) a plastic feed wheel for aluminum and a Teflon liner for the gun/wip

Don't know how well the 151 welder will do on aluminum. or what you may need for ALUM.

myshtern,

Whichever mig unit you choose, make sure you use shielding gas if you plan to weld exhaust tubing rather than flux core.
You will have less trouble with burn through.

I havent had much time lately to focus on welding, but I'm back in the game

I am really leaning towards this welder:
http://www.harborfreight.com/cpi/cta...temnumber=6271

Whats the difference between that 151 and this:
http://www.harborfreight.com/cpi/cta...emnumber=55236

Which one would you buy? (Look at the price difference)
Why?

Thanks again

Exhaust gases arent that hot I think.
4 cylinders on a daily driven car, dont generate enough heat to burn through the metal.

Your late that HOBART welder was $329

If I was going to go cheap maybe this one $159
http://www.harborfreight.com/cpi/cta...emnumber=55250

I would go with a cheap one, only because I'm good with fixing most anything.
I'm currently making a new wire feed unit for a 110 volt L-tec mig welder, I got for $20.

other than the feed units I think the cheap welders can be good.
maybe the 151 has a good feed unit, you need to ask someone that has one.

GregH, was talking about burning through when welding, not the exhaust gases.

Thumbs down

I looked at this xxxx earlier today. It's a bonified xxxx! I cracked the case to see what was inside. Cheap plastic, metal, design, etc... You get what you pay for. Save up and buy a Hobart or Lincoln.

Don't buy the harbor freight welder (chicago electric) It is JUNK I have had the displeasure of using one. I spent more time clearing wire jams then welding. Parts are very hard to come by and the 15% duty cycle is more like 5%. I have not used the Hobart mig welder but it is a good name and parts are easy to come by.I bought a Millermatic 130 used for $300 and am very happy with it. Esab and Lincoln are also good names.If you don't want to pay full price try to find a good used one.the harbor frieght welder I used was just an over priced boat anchor.I have purchased tools from harbor frieght that are just fine but the welders will like I said boat anchor.Good luck with what ever you buy. MIKE
