Title: Welder Extension Cord
Post by: connor0770 on March 31, 2014, 07:39:31 PM
So im picking up a welder this weekend and need to build an extension cord.

Its a Lincoln 180HD 220V with gas.  I was wondering if I can get away with 10/3 SOOW wire instead of 8/3.  Kind of on a budget.. Some guys have said they buy the 100' contractor 10/3 wire and chop the ends off for 220.

Any ideas?

Heres what ive found:

Can you?  Yes.  Should you?  No not really.  I certainly wouldn't get a 100' one.  But for starters you'd be ok for a little bit.  Try to find a RV extension cable on sale somewhere, or used on craigslist.

Like this one..... http://reno.craigslist.org/rvs/4384905013.html (http://reno.craigslist.org/rvs/4384905013.html)

You could use the 10/3 safely if you change the breaker protecting the circuit to a 2 pole 30A. FWIW i ran my old miller 175 off a 20A circuit. Only tripped the circuit once in 2yrs. Checkout cyberweld...they sometimes have smokin' deals. I bought a 25' 8/3 for $64 last year. Ive been doing electical work for 14 yrs :thumbsup:

I trip 20a breakers quite often with my little 110 welder.

current draw from a 110v machine is higher than that of a 220v machine at similar output levels. Are you working with that 110v cranked up?

I converted a 50A (Shhh!) Docutech 15' cable for my welder. I gave it to autumnxtoxsehsa when I sold him my welder. I know he got rid of the welder, but he might still have the extension cord.

so i should really shoot for 8/3?

what size breaker is protecting the circuit? If 30a, 10awg. If 50a, 8awg.

Family friend has a 10/3 already set up for my drier that he's gonna let me use! Pretty excited.  The welder comes with a full bottle of CO2. Any chance airgas will let me trade it in for a CO2/Argon mix?

If you pay the difference lol no probably not wat are you welding? Co2 is fine for steel

never tripped my 220v welder on a 20 . but now i have it hooked up to a 220v/30amp receptale and use a 10/3 cable.

i would only go bigger if you need a long cable where voltage drop would be a problem.   when i hook up welder feeds for
on the job they always spec 50 amp recptacles and #6 wire. but for or size welders its way over kill. the only time i ever tripped a breaker was with my old stick burner cranked way up to burn holes.

I have a 50amp plug in my garage.  I have 25ft of 10/3 .  My welder can pull 250amps. The welder cord looks massive. Like a garden hose.  Is 10/3 gonna cut it?

Post by: timatoe on May 05, 2014, 09:43:46 PM
I re-looked at my original post and I'm pretty sure I was thinking 12/3 with an extension cord.  I have a 25' 10/3 that started life as an RV extension cord, I think it's more than plenty.  I would run it even with your new machine Chris.

10/3 is fine.

So I wired my 10/3 cord tonight to my 4 prong dryer.

My setup is a 15ft cord to a 25ft cord on a 30 amp breaker. Think I'll be alright? I'm only skeptical about using 2 cords but I have to.

First weld


6 or 7th weld.   Love this thing (http://img.tapatalk.com/d/14/05/14/3e8a6y5e.jpg)

Any suggestions? I'll take all the help I can get. I know my penetration is good. Just need help on a more consistent bead

Those don't look bad at all.  What pattern are you using?  The second pictuee is hard to tell but almost looks like undercut from too much heat. 

You just nees to practice a ton.  Get a good pair of gloves so you can hold the gun comfortably and brace your hand while welding.  Make a dry pass to be sure you will be in a good position the entire bead.

90% of the time I move front to back.  I vary how much by the puddle and how the wire is laying
  You can stack dimes that way too by a quick forward and a slow back.

I have a good pair of gloves. There's actually very little if any undercut.  I'm using the circle method. Kinda like a roller coaster. Hard to explain over the forum but you should get the idea.

My penetration is good due to the color on the steel. My biggest concern is getting that "dime"formation.  Huge improvement over my 110.

It's 1/8 steel and I turned down the heat a bit. I was following what the welder says but it's just too hot.

I think those are very nice looking beads for a first few tries.

Agreed with Tim n Chris.. just get em tighter closer together be good to go lol.. learning mig first is cheating all welders should learn arc first haha

I learned to ARC weld in Reno. Got "okay" at it. Then bought a 110 and played with that. Now that I have a 220 it's 100x easier

It looks like your running to fast and far spread out (or your wire speed is to slow for how fast you want to go). Your over penetrating on the flat and maybe under penetrating on the angle which is common when you first start out its normal to want to spend more time on the flat piece then the part sticking up. If you want to come by my house i have a book from a class i took that has all the basic techniques if you want to borrow it.

thanks schoner! Like I said I'll take all the help I can get.  I'm currently in Chico so I doubt I can swing by. I'll take what you said into consideration next time I practice.

What your saying is i need to spend more time on the vertical piece with my puddle and less on the bottom?  Also slow down? 

I'm using exactly what the welder tells me to use speed and heat wise.

you also want to listen to the sound. a good sounding weld should sound like bacon in a frying pan. But yes make sure you even out your time the only time you want to spend more time on one piece vs the other is when one piece is thinner then the other. and like sated before try the c pattern its one of the best for mig. or if your traveling up a weld joint you can do the z but that takes a lot of practice. i will see what i can do with maybe scanning some of the pages for you from the book.

here are some patterns some are useful but some are more for certain jobs

Yea it noticed to closer I got the better the bacon sound. Learned that one real quick.   I've been going top down on my vertical joints in a Z pattern. Those welds look great, but everybody says those are the easiest
