Rated 4.7 out of 5 by 41 reviewers.
Rated 5.0 out of 5.0 by Great Welder! I love my Lincoln Electric AC/DC 225/125. It's a great versatile machine, reliable as all get out and gets the job done right. With Lincoln electrodes, there's not much you can't do without this welder. I'm so loyal to this machine that I didn't bother upgrading to an Idealarc 250 because I was so satisfied with my AC/DC 225/125. Everything the other reviewers said is absolutely true. The bottom line is that this is a machine that always gets the job done and never lets you down. It's worth every penny. Given that Lincoln Electric machines are so well built, it's not uncommon to see 30 year old AC/DC 225/125's still working perfectly. Definite 5 stars! June 15, 2011
Rated 5.0 out of 5.0 by Excellent Price I read the reviews before purchase and was a little hesitant but finally purchased. This is a great buy probably saved 350.00. I contacted HD and they informed me it was a new welder not refurbished and it did have a small dent or 2 in cowling but a dead blow hammer straightened right into place. Don't know why they had such a great price I am sure there is a story behind it but for a welder that will sit in a shop you can't go wrong. Came quickly delivered to house excellent contact with HD personnel. Plus I received 12 months interest free to pay off, If you know your welding you will know this is a great buy. December 25, 2012
Rated 5.0 out of 5.0 by Great welder and price I ordered this welder Wed. evening and picked up at store Friday afternoon. Very fast shipping and arrived in perfect condition with zero dents or damage. Everyone at Home Depot was very helpful. November 30, 2012
Rated 5.0 out of 5.0 by By design, the DC side has finer amperage control. I am a retired Boilermaker pressure-parts welder. When I retired; I had 22 different welding certifications to my credit. I love this machine! You can weld a great number of different welding rods.308-16L on Ac & 7018 on Dc reverse are two of my favorites. October 11, 2013
Rated 5.0 out of 5.0 by Awesome "work horse" welder. This is a basic work horse welder. The DC mode option is great and this machine can dish out the spark all day long. I have high dollar welders in the shop, but I needed a basic no frills stick buzzbox, with none of the "gingerbread" found on other expensive welders. There's no need to have a stick welder with all of the bells and whistles on board if your a home hobbiest, farmer, rancher, metal artist, plumber, carpenter, handyman, welding student at a tech school or even a professional for home use. Unless your into production welding or ship building, this welder will fit your needs. For thin stuff less than 1/8" thick however, this and pretty much all stick welders is NOT for you. Stick is not intended for thin sheet metal under 1/8". Even then, use 3/32" 6013 electrodes on DC- for the thinnest stuff. Some say that the "tapped" amperage control is not as good or "fine" as a continuous setting like the Miller Thunderbolt or Hobart Stickmate. Well, so what. The difference in amperage adjustment is negligible. I doubt two welders side by side could tell the difference apart of each's weld beads when comparing their machine to a Lincoln AC/DC-225/125 machine. One I'll say is that stick welding does have a BIG learning curve to get descent (slag inclusion free) welds. Practice practice practice and watch online videos on proper technique and electrodes to use. Also, make sure you have a 50amp 240 volt electrical outlet installed in your garage. It requires a NEMA 6-50R type receptacle that your electrician will know how to install. Try to avoid the "30 Amp" "dryer" outlets. Sure it will work, but not at 2/3rds or full power when needed. Home Depot has a pretty good price on these Lincolns. Buy one, you won't be sorry (if you practice a lot)! November 14, 2013
Rated 5.0 out of 5.0 by It's a Lincoln what can I say I have been welding for 35 yrs. If your looking for a arc (stick) welder, look no further. This machine can weld up to 5/16-7018 (Low Hydrogen) and up to 3/16 Mild Steel. You can even carbon arc (back gouge) with 1/4 inch carbon rod. If you have an air supply that is. Yes, there is bigger (amps). But if your not building a ship. This is the machine for stick welding!!!! July 29, 2006
Rated 5.0 out of 5.0 by Expensive but worth every penney. easy to install and worked great. Just what I wanted and will be used a lot. September 16, 2014
Rated 5.0 out of 5.0 by This welder does everything I need it to do. Home Depot had the best price for this model welder. I am completely satisfied. The DC arc welds nice and consistent. I would recommend this product to any one. January 9, 2013
