Rated 5 out of 5 by from Better than advertised I confess I won this welder as a prize in a contest not run by Miller. Miller and Hobart are now under the same company. The case on the welder and its dimensions are identical to the Hobart Handler 125EZ (flux core only) welder I bought as a factory refurbished unit seven years ago. So far, I can tell the gun, driver roller assembly, and ground clamp are diffeent. The 125 Hobby also has independent wire speed adjustment. The 125EZ is auto set only. I normally weld steel 1/8" in thickness or less, but there is an occasional weld on thicker material. The first photo shows a test weld I did on a piece 5/16" to a piece 5/32" in thickness. I welded a bead on both sides with no chamfering to make a "V" for a root pass. When I cut across the joint at a right angle and polished the cut with a file, I could see no signs of a poor or incomplete weld. Although not recommended for materials thicker than 1/8" with solid wire and gas shielding, I will weld thicker materials with it now and then, although I will likely prepare the joint with a "V," a good root pass, and some preheating to further extend the capabilities of the welder. The Jerusalem cross of cut nails in the other photo is more typical of what I normally do. The nails are held together with small tack welds from behind. I have a couple of jigs I made to hold the nails in place. On this cross I used the recommended voltage setting of for 1/8" and recommended wire speed setting of 45. The settings were almost a little too hot, which was a nice surprise. Flux core welding makes it hard for me to see where I am welding. I found it very easy to make a very good looking bead as seen in the first photo. Part of that is just a difference between MIG with gas shielding and flux core welding. Flux core makes a lot of smoke that hinders the view of the weld puddle and MIG can be pushed so the arc lights the joint ahead of the arc. I am very impressed with this machine. It feels like quality. Setup and use of it are both easy, although I did momentarily panic when I thought I was missing a gas fitting for the back of the welder. At first I did not realize a red plastic thread protector needed to be pulled from the inside of the brass fitting on the welder.

Rated 5 out of 5 by from I like it. I got this welder from my family for Christmas. I am new to welding and am currently taking my second welding class at a local community college. So far I've really enjoyed using this welder. I built a welding cart for it, which I'll include a picture of. At my class, there are some more heavy duty Miller welders. Eventually I'd like to purchase one in order to have more versatility. But even when I do, I think I'll still keep this welder because it is convenient and easy to use. So far I've only used fluxcore wire on it. I'm excited to get a tank for it and see the difference with gas.
