CAN THIS WELDER BE POWERED WITH A GENERATOR

I'M NOT ELECTRICALLY EDUCATED ,SO THIS WILL PROBABLY SOUND LIKE A DUMB QUESTION , I HAVE A TROY-BILT 7000/10500 WATT GENERATOR AND A SMALLER 4000 WATT TROY-BILT , WILL EITHER ONE OF THESE POWER THIS LINCOLN WELDER, DOES THE 4000 WATT SMALLER ONE HAVE ENOUGH POWER FOR THIS UNIT. i KNOW THE LARGER ONE WILL POWER MOST OF MY HOUSE, AND I WOULD THINK A WELDER WOULD BE NO PROBLEM FOR IT, BUT I CAN'T FIND A STRAIGHT ANSWER TO THIS QUESTION, AND i DON'T WANT TO DAMAGE THE GENERATOR OR WELDER. THANKS FOR ANY HELP

Extension on leads

I was wondering how i could extend the leads because i heard they were short and you practically had to hover the machine.
Asked by: Tyler
The length of the cables on the AC225 out of the box are 9ft and 11ft. To extend the cables see part # kh554 and 4 gauge welding cable.

How long are the cables and can you add longer ones safely?

Asked by: Maxb
The AC225 comes with an 8', and a 10' lead. You can extend them, but need to follow amp/guage charts for the length required.

AC225S Arc Welder is rated 4.7 out of 5 by 34.
Rated 5 out of 5 by from Lincoln AC 225 I've been a welder all my life. I went into management for a period of app 28 yrs and sat on the sidelines as the younger guys did the welding. Now semi retired I found myself needing a welder. I went back to the welder I first used when I was 15 yrs old ! The Lincoln AC 225. It's 5 star. It'll do the work. And I haven't forgot how to weld ! It'll weld 7018 LH rods, 7014, 6011. And it does an excellent job. It's not a $5000 machine, but I don't need one. I highly recommend it. Knowing how to weld is not a plus: its detrimental. Much to the chagrin of some, it takes a "weldor", not a "welder" to be able to weld. You young guys out there: get 2 yrs of welding school under your belt. Get certified. You'll NEVER be out of a job ! And then get this Lincoln. In your spare time people will line up to get you to fix something for them.

Rated 3 out of 5 by from Can't fine tune The welder is great but the only down side is you can't fine tune the amps. You can only weld with the pre selected amps that are shown on the welder.

Rated 5 out of 5 by from Better than a $2,000 welding machine Seriously it's better that a $2,000 machine. I've welded for 5 straight hours and it never stopped.

Rated 5 out of 5 by from Welder Works perfectly, does exactly what it's supposed to.

Rated 5 out of 5 by from Simple, powerful, quality and great value. I purchased this welder from my local Home Depot and it exceeded my expectations. You can't find a better value anywhere. Straight forward layout. Strikes an arc with ease. Built to last. It's everything you'll ever need to do most welding projects and it won't suck your wallet dry. This is Lincoln's best selling model of all time...and if you purchase one you'll see why. Novice or pro...you'll be very pleased. Nowadays it's hard to find a good quality product that does the job it was intended to do and doesn't cost an arm and a leg. Kudos to Lincoln and Home Depot. Would recommend this welder in a heartbeat.

Rated 5 out of 5 by from BigT After 40 years of long and faultless service, my old machine is needing a rebuild. I love my ol machine. Have welded everything from body metal to antique car frames to 3/4 iron bar.If you get one of these tombstone welders, you too will be happy. Just a good solid machine.

Rated 5 out of 5 by from Purchased THIS welder OVER 25 Years ago and, STILL WELDS GREAT!! Purchased THIS welder OVER 25 years ago and, STILL welds GREAT!!! I have had Trucks all my adult life and, heavy equipment too for a while. Never been a "wealthy" man so I have always bought used equipment and, fixed it myself! And, I can tell you first hand THIS Welder HAS the POWER to penetrate HEAVY Metal! Always be sure to clean ALL your surfaces! (ground too) The Trick to getting it to Stick is PENETRATION!! The ONLY other thing I can say is that I have never had any formal training as a welder but, I NEVER had ANY weld fail. NEVER! Again the trick is PENETRATION and, CLEAN your surfaces! That being said, many "REAL" welders (like certified ones) have told me that IF I liked welding with THIS welder I should try the AC/DC version. They ALL say the DC welder works better and, is easier and, makes a nicer weld. Well after I returned to Pittsburgh from NC. I went to work for one of the local trucking companies and, they had an AC/DC version of this welder and, I used it many times and, I can NOT honestly tell you that I noticed any appreciable difference what so ever. Maybe it might have been a little easier to get the rod started. But, I never really had any trouble getting a rod started anyway. Please DO NOT HESITATE for one second. THIS IS A GREAT WELDER! It has NEVER let me down!! NOT EVER!! 26 years atleast! And, I have NOT been nice to it either! Run it hard and, long and, under harsh conditions too! NEVER a problem. GREAT WELDER!

Rated 5 out of 5 by from Great product at a reasonable price. Welder does a great job around my ranch. Just the right size for my needs. Even welded 5/8 steel with surprisingly good results. Easy to use. Burns stick after stick with no issue. Highly recommended.
