The machine works great. I tested that it can weld copper. Though it came with broken reductor, Tooltos sent me a new piece. Happy with my purchase
Is unbelievable. It works perfectly even without connecting a cylinder, and came with many Tungsten tips of different thicknesses and even with a little motor to sharpen them!! I tried it on brass and it works great. Only to say that it came with things related to argon but that it does not indicate what they are for, and that it comes without a microscope. But it's still a 10/10 for this price. In addition, it came within 2 days of having requested it, despite the fact that it indicated a date of receipt of more than 25 days. All fantastic
Very happy with the product and the service received!
