Rated 4.7 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by best for its price range I got this for my birthday and this thing awesome . It has done everything I've wanted it to do. I got it so I don't get rusty when I'm not gonna be at boces for a while. I haven't reached the duty cycle yet but I think that's because I trip the breaker before layin down a whole rod. I've welded only mild steel so far but it says it can weld up to a 1/4inch thick steel and lemme tell ya that's a lie. Today I welded half inch steel and it got plenty of penetration and it was perfect. I used 3/16 7018 and 6013 and I've used 1/8 6011 and it worked fantastic. If you're lookin to buy a 120v stick welder this is the one you should buy with out a doubt. And century is owned by Lincoln so you know its good October 5, 2012
Rated 5.0 out of 5.0 by Above and beyond I purchased this product to do some light sheet metal work on a vehicle I am restoring, boy does she work like a charm, the low duty cycle is an issue but this little unit is great. I also found that it is far more than capable of welding up to 3/16 or 1/4 inch steel its not limited to only 1/8 inch steel. Great little unit I would definitely purchase it again. March 12, 2011
Rated 5.0 out of 5.0 by For a 110 welder this little machine is great Ive done alot of welding with this little jewel. I find myself using it as much as my lincoln 225 220 volt welder. Most of my welding has been utility trailers and snow plows for lawn tractors. and a few repairs on a 8N ford tractor. Ive welded 1/8 to 1/4in pipe and had excellent results. The most important thing to remember is. The welds you do depending on the rod you use,(6013,6011,6010) will have atensile strength of 60 thousand pounds per square in. ( welded properly) I wouldnt try welding a backhoe bucket with this machine but for building 5x8 utility trailers, Excellent. Im the kinda guy who will stretch a machine to the limit and beyond so ive been impressed so far. Id recommend itto a beginner or a veteran welder if it were the only choice. Of coarse a veteran may have a better unit but just sayin. December 31, 2013
Rated 5.0 out of 5.0 by building a vw trike really suprised me does a great job even on 1/8 rods August 5, 2015
Rated 4.0 out of 5.0 by Awesome purchase This is an awesome purchase. The power exceeded my expectations in every way. I would recommend this machine to anyone that needs a powerful and portable welder. April 21, 2015
Rated 5.0 out of 5.0 by This machine runs great! I have been welding for over 12 years and have never used a 120V welding machine. I was impressed at how well it ran and how it performed. All in all, great buy! January 29, 2013
Rated 4.0 out of 5.0 by Worth the price This is a good welder for what it is. It is perfect for what I wanted. It does short welds on light material. It's low duty cycle limits its usefulness, but I knew that when I ordered it. I like it and would buy it again. January 24, 2010
