I have 12 gauge wire leading to the outlet.

AWG 12 is rated for 20 amps. {Resistance Ohms 5.4/km (E=IxR)}

Do I have to rewire it with AWG 10/3?

I have the same one, and have done a lot of welding on a GFI 20 amp circuit. I don't think it will be a problem.

My buddy has one of those. Great little machine. Makes lots of spatter though.

At the price they sell it for, it is practically a hot glue gun for steel.

Don't listen to me though, I only have a 120v 70 amp ac stick welder.

I like the hot glue gun analogy.

at www.weldingtipsandtricks.com

I subscribed to a sequence of some daily emails entitled

"Big Fat MIG Welding Myths"
----------------------------------------------------
Here is a partial copy of one of those.

Quote:
"""
Big Fat Mig Welding Myth #5

110v mig welders are toy welders and are not good for anything.

110v mig welders are not toys unless you get a really cheap and poorly made welder.

If you buy a good one like a Lincoln, Miller, or Hobart, they are pretty handy.
Sometimes even cheaper ones from Northern Tool or Harbor Freight work ok...but not always.

They typically use .023--.025” wire and that works great for thin sheet metal body panels.
But what about thicker stuff?

That’s what flux core is for.

Swap over to
Hobart fabshield 21b and you will be surprised at the results on
thicker metals.

Tips to get the most from your 110v mig are:
decrease wire stick out,
clean the metal with a grinder,
use flux core on thicker metal, use a 20 amp breaker,
preheat with a propane torch and weld uphill.

And by the way... if you need to weld a trailer hitch,
dont try to use a 115v mig.

110 volt MIG Welder Spatter

Occasionally I come across a product called "Nozzle Gel"
http://www.amazon.com/Hobart-770074-Welding-Accessory-Nozzle/dp/B0017Z5J1W

Product Description by Manufacturer:
"Prevents adhesion of weld spatter to MIG nozzle and weld surface."

Anyone ever try HTS2000 on motor mounts?

I tried on my boat rivets and works wonders but gravity dippers

For boat rivets I should of tried there older generation brazing rods that melt at lower temps it warped bottom alittle. I even made a new boat drain with this stuff and had to hammer a socket threw it because it warped and it held up

IMHO the key to reducing that is to buy NON-HF wire. I have Miller, and it helps a lot.

Lincoln Super Arc L-56 wire is the best.

Nozzel gel? I use it daily when mig welding.

Get the nozzel hot and dip into the gel. Let it drip off, advance the wire and trim the wire. Weld away. Spatter does not stick to the nozzle.

PAM works as De spatter and smells pretty good while you are welding. You can spray the nozzel with pam too.

They make a spray de spatter that works fine and you can spray the nozzle with it too. Both the spray and gel work. It depends on the job I am doing.

I THINK the best flux core wire is NR211-MP You may not be able to find it in the size for the machine.

Smaller wire costs more, but for that machine its better.

YES I agree, Lincoln is the best wire.

David,
When you hear the bells toll you know where the church is.
I bought a 1 lb spool of .030 Innershield NR-211-MP at Lowes in Syracuse
on the way home from Harbor Freight (within a mile from HF).

Lincoln Electric .030" NR211-MP Flux-Cored Welding Wire
Item #: 178739 | Model #: ED031448
http://tinyurl.com/62c3meh
The Lowes picture shows no markings
This is the Lincoln wire I bought:


I am in the process of fixing a separate circuit in the summer kitchen attached
to the house with AWG 10/3 near the door about 15 feet to the main entry.
The power cord (AWG 14/3) on the unit is only 6 feet so a short extension cord will still be needed.

Local power company is municipal. Great rate.
But they sometimes drop the line voltage to save some money I guess.

Forty feet between the house and the garage panel, plus adding another 26 feet for the wiring in the garage/shop.
I view that with some skepticism.

If I had money I would invest in a Bulldog 5500
http://www.lincolnelectric.com/en-us/Equipment/Pages/product.aspx?product=K2708-2

Maybe I can sell my 16k PTO driven generator on a cart which I don't need anymore.

Interestingly inside the plastic envelope containing the manual is a small 2 x 3 inch snaplock bag.
It holds a Lincoln Electric MSDS (Material Safety Data Sheet) No. US-CW140
for Innershield NR-211-MP. Dated 2/15/07.
It has since been superseded by one dated 7/7/2010.
http://lincolnelectric.com/libraries/msds/US-CW140.pdf

Makes one wonder if the wire supplied is a Lincoln Electric Product.

George

NR211MP changed a few years back. MP stands for multipass and it had something to do with that. Its a true ET71-11 wire. It used to be rated to 5/16 inch, they changed it to 1/2" Most big box stores welding wires are ET71-GS which is no aws rating.

First off thank you all for all the great info, advice and links.

I inherited a Millermatic 175, just got one problem with it, sometimes the wire will weld itself to the liner just past the feed roller bringing the welding to a stop. Is this terminal?
I put a new liner in, no help, any help from any of you guru's?
Or do I just need a BFH?
Someday I want to sell this turd and get me a Lincoln so I can run a spoolgun.

My New/Old Welder

I just stumbled onto this thread and have read the first 50 pages so far. Gotta thank everyone who has participated as the wealth of information is incredible!

My question is, I recently acquired this welder, it's an early 60's Hobart AC/DC Tig/Stick model ADI-264. I have fired it off and so far have only used it for stick welding. And it does put out a purity weld! I believe I have all the pieces to get the Tig operational, but I would like to first acquire any literature that's available for it. I recently wrote to Hobert, but I was also hoping someone here might have some info on it.

I'm fairly new to tig welding, but I have been stick welding for 40+ years both on a professional level, and home hobbyist and I know the basics for both mig and tig, I would rather read up on this particular machine before diving in.

Any help any one can offer would be greatly appreciated.

wanna start

I'd really like to get started welding as a hobby, maybe make some racks for my bike, build some stuff around the house and whatnot, make a cool welding cart, etc. it'd be really cool to build some frames for bikes, bicycles, maybe a trailer?

was hoping to buy something on craigslist for not too much money, maybe $4-500. what should I be looking for, what would be the best avail for me in that price range? thanks

Marc
