Excellent little welder !
This welder is great easy to use and I’m surprised of how good welds, definitely worth the price ‼️

Perfect for small projects.
This little welder works great for its size,I'm impressed with it.

Great value overall
For general shop fab work and farm repair this unit is perfect. The Hot start works well, lead length is appreciated although the ground clamp is cheap and would need to be replaced if welding pipe or larger tubing. Easy to move around and takes up much less space than my old transformer welder.

The dimensions in discription are for the package.
The media could not be loaded. I was happy with the way the machine was packed. They were generous with the power input cable length. The large dinse connectors are a nice touch but the stinger is generic.

Solidly Built
This seems solidly built and it has the large dinse connectors, I expected them to be the small size. I cannot speak for the longevity of this unit but as long as it continues to run the way it is I will be happy. I welded 1/4" thick steel plate with 1/8" 7018 no problem. The lift start TIG feature works great, it starts easy and runs extremely smooth. ... show more

Lovable welder
Very high quality machine, especially for the price. Smooth as glass with 7018, and will run 6010 as well, tho you do have to be mindful of arc gap. I did upgrade the stinger and work clamp, almost immediately, but the cables it comes with are top notch. No reason to change those.
