## Description

Great tools at a great price

Review: Great little welder - Works great
Review: Awesome machine no matter your skill level. - First let me say that I am not a professional welder but this machine sure makes me look like one. I have used both the wire and stick welding processes on this machine with impressive results. I don't know anything about TIG welding but plan to learn in the near future. The settings on the inside panel make selection of settings simple. I have a large Fourney welder that has been passed down from my grandfather, but it doesn't work well with anything smaller than 1/4" and only does stick welds. Wish I would have bought this years ago!

### ⭐⭐⭐⭐⭐ Good for the home shop
*by M***Y on January 8, 2023*

Bought this welder for my home shop. Hadn’t welded in years. Took a while to educate myself on the set up but once you get it going it’s like anything else you just have do it a lot to get good at it.you tube videos are a great learning tool for this. I like the versatility of welding sheet steel and being able to switch to the stick welding for heavy steel. I am looking forward to trying the tig welding capability. All together a great tool!
