A buddy of mine who is a welding instructor showed me this brand. He had never used one before and he told me it is a great deal because it is way cheaper the comparable mig welders from Lincoln and Miller. Anyway I got it and it is downright awesome. Took me a little bit of time to get used to it, but after the learning curve everything is wonderful. The spool gun is great. I had a lot of aluminum that I needed to do. It did a great job. I tell everyone that I know about it.
