I'm really enjoying this machine. Using the plasma cutter it cuts 1/4" thick metal clean, like butter. The Arc Stick welder function is smooth. I don't have much experience with TIG but since it comes included as a feature of this machine I decided to pick up some Argon and try it out. I'm having fun learning to TIG with this, it will not do aluminum since you need Helium to TIG aluminum with a DC TIG Welder and even then it's not recommended. The Torch that comes included is a WP 9, you can purchase a WP17 for this if you like those better but for the amperage that this machine works at the WP 9 is more than enough to handle. This machines comes with everything you need right out of the box except for the Electrodes and Argon gas if you plan on doing any TIG welding you'd definitely need some Gas.You will need to buy Tungsten and Arc Stick electrodes to do any welding with it. The collets that come with the TIG Torch will only accommodate the .040 and 1.6mm Tungsten so I recommend buying some additional collets or gas lenses if you plan on using the more common Tungsten sizes, though the smaller electrodes are cheaper and I ordered a pack of 10 in size 1.6mm (1/16") electrodes for $10.99 which I linked to below.https://www.amazon.com/gp/product/B01H0M1838/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1EDIT: I wanted to mention that you should run the plasma without the little wire standoff that comes included, it would make the plasma torch skip across the material, without it the torch goes smoothly over the metal. I also run the Air Pressure at 60 PSI, if you run the air lower than this it will not cut as fast or as smoothly.
