CUSTOMER REVIEWS

Rated 4.8 out of 5 by 28 reviewers.
Rated 5.0 out of 5.0 by Quality Pros -clean welds -easy to strike an arc -excellent price -good penetration on welds -easy to transport with a dolly -whip and work and welder are all well made Cons -no dial -- only eleven amp settings -whip, work and plug-in cables are a bit short Overall: very good product, excellent price and user friendly. Would definitely recommend this. For anyone new to welding I would recommend any size of 7018AC welding rods. June 5, 2014
Rated 4.0 out of 5.0 by preferential product recomendation I have owned and used this product for a few years now and strongly recommend it to all welders of varied skill levels. It is easy to use from the novice and has the power for those with higher demands. I should say that I am not a welder by trade but my friends and family are, and they frequently use/borrow my machine. This is my second welder. I upgraded from a 110volt unit that just did not have enough power for my needs.(it wasn't a bad unit just not heavy enough for what I frequently do) The 225 has good iternals that have held up well. It has been used for mostly ferrous metals, from very thin to upwards of an inch-with several passes. If, I had to comment on one thing that may be of some concern to it's buyers and end users, it would be the cycle time, while plenty for me, may be of concern to someone usig it on a commercial basis. Having said that, I think it auto shut off twice (which isn't a bad thing). One other thing I would change from a design pespective, would be the length of the handle, I personally find it too short; an adjustable one would be more practical for more users. I did change the electrode holder for a 400amp handle type, and found it more suitable for my needs(local welding supply store for $15-no biggie-and the guys really like it too). Having said all that, my main uses for the welder are light fabrication and general auto/truck and yard repairs. If you are in the market for a relatively inexpensive general purpose welder, I would suggest trying this out before buying others-even if they are cheaper or more expensive, this really is a great little machine-at least i think so and carries a good warranty. And, no I don't work for Lincoln or any of its subsidaries-just a happy consumer-and there aint many of us out there these days.When was the last time you bought some thing that you actually felt you got a value?

Rated 5.0 out of 5.0 by 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! October 9, 2013
Rated 5.0 out of 5.0 by 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. January 6, 2015
Rated 5.0 out of 5.0 by 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. February 19, 2012
Rated 3.0 out of 5.0 by this is a good product This is a great welder.I just bought my 2nd one,my 1st one was over 40 yrs old,however I believe they could be less greedy about there lead cables.Unless you add longer ones they are pretty much worthless you have to hover over your welder to work on anything. February 2, 2013
Rated 5.0 out of 5.0 by Certainly out-performs my old welder by far. I like the features better than my old welder. Unit activates immediately, no waiting. Burns clean. Leaves good weld. May 4, 2014
Rated 5.0 out of 5.0 by Lincoln AC225S Welder we looked at a lot of welders before buying a welder at The home depot and glad we did this is one of the best welders I have use in my life and I have work on a farm and use all kinds of welders over the years and you can not beat The home depot Price on this welder. Thank You home depot June 21, 2007
