5.0 out of 5 stars User-friendly and works well
Reviewed in the United States on October 30, 2021
This welder is tiny, lightweight, and works really well. Adjustment is a simple dial with an LED display to show what the amperage output is.

I essentially can't weld, since the majority of my experience was decades ago on fluxcore MIG gear.

I started with 3/32" 6013 rods, thanks to advice from my buddies. Some dial fiddling was called for, but soon I was putting down horrible beads on some 1/8" plate. The penetration was poor and the beads didn't seem to go where I aimed them.

A quick peek at a YouTube tutorial, and I adjusted my amperage way up. Now I was making ridiculous wide flat beads and blowing holes all over my plate. At least now I wasn't false starting nearly every bead!

A little bit more fiddling, and I was able to put down a good looking bead. Filler insertion into the parent metal was good, too.

This welder runs well with only 110v input. It has survived all my clumsy learning efforts and many mistakes without a hitch. It just starts and goes. Once I had technique and selecting amperage down better, I was able to get good results every time.

Now I am able to weld thinwall tubing with it. It does square section tubes with ease, but round is a bear. Results, however, are well worth the trouble.

What this all leads up to is, If I can weld using this machine, so can you. It would be a great hobby or light duty welder for someone who actually knows what he's doing.

I recommend this good little welder to people of all skill levels
