Very pleased with this welder!
This is a great little welder for the price point. I am very impressed and pleased I selected this particular unit. It wasn't easy. I based my decision on feedback and reviews from other buyers. The only complaint I have, and it's pretty significant, is there was nothing on the package to show me how to set up. No instructions whatsoever. Most people buying welders have previous experience but not all. So this was a real bummer. I had to go on the net for help and that was even difficult. Finding this exact model wasn't happening. So I had to use several different postings to get it set up. Besides this oversight I highly recommend the Sunstac 150A welder to anyone looking for a light weight very portable welder that gets the job done!!

Very good quality and quantity for the price
Unboxing it seems made pretty well actually I'm sure you can't beat it for 75 bucks especially with a stick lead and a mig handle the spool of wire is like a half of a spool but we're not going to complain about that it's honestly a great deal for $75, I'll buy the larger gas version next time.

Much better than expected.
I have been welding for years and always believed in high quality equipment. Needed a small welder for a remote job that could hook up to a small Honda generator. Saw the reviews, so gave this a try and I couldn’t be happier. You aren’t going to fill gaps on 1/2” plate for 10 hours a day, but this may retire my oversized Miller welder in my garage for small projects.

Go online and find the video how to setup the welder before you use it. The instruction comes with the unit doesn't show very clear how to connect all the cables, especial the negative cable where it goes. However the unit works great when you get it setup right.
