Fired it up for the first time today. So easy to set and dial in. So easy to get right to the point and get to work. All the accessories are completely top-notch. Set my dials and got to work without a single hiccup. I'm not an advanced user - and this machine took so much of the initial guess-work out of the process. I did in minutes what would have taken me an hour or so with my old TIG rig. I couldn't be happier.

Wow! CK worldwide did a great job on this…
Wow! CK worldwide did a great job on this machine! I love that I can use it on 110v and 220v! Super crisp start with so hesitation. Comes with everything you need to weld like the pros(minus gas and filler). Im very impressed with the abilities it has with all the adjustments to tune it just right for all your welding needs. Welds aluminum great. No issues. Only thing that I don’t like due to personal preferences is the bulky foot control/pedal. It works well and super sensitive but I’m used to the miller style ones. If your looking for a good little machine for daily use or something small to bust out when you need it buy this! Check out some work I did with it on my Instagram @Mishler_made_fab

After spending nearly a year making money with this machine, I would recommend it to any and all. This complete tig package has everything you need to get going and start turning out work immediately. Great value, great accessories, high quality torch and all the bells and whistles. One thing everyone wants to know is, how is the AC ???? Let me tell you it’s good... really good. There is lots of AC adjustment for a machine in this price range. For me, another favorite feature is the dual voltage. I can run on standard 110 and it really saves me on my electric bill, which for a shop owner is big. My only knock is the rather bulky tig pedal (ghostbuster stomp box), but I can look over that for the great price and everything else is top shelf. I recently water-cooled this machine and upgraded to a more industrial torch. This thing is a serious work horse now, and I am loving it. Find me @Moser_fab on Instagram to see this thing in action. Thanks, Jason Moser.
