We I should say powertig 144 to 650 .yes I bought a 185 through pricesmart (costco ) here in panama and when I got it home plugged it in and on low setting had 144 amps on high 650 .if I struck a air at 650 the over temp light when right on and the machine did not work . Contacted service and they thought it was a board that was bad and rushed me a new board , after I installed the board it fixed one prolbem but created another , the machine now showed on the digital display the right numbers but would not strike a arc at all . Lucky pricesmart has a 30 day return policy for full refund and then a 11 month policy were they can repair or replace .I was in the 30 days so dumped it on their lap and ordered a new one and low and behold it works great .I was very disappointed at Everlasts answer that I would have to pay shipping back to them .if a product new out of the box does not work why should their customers have to return their crap .if it works for a period of 2 to 4 weeks then craps out then I could see the customer having to foot the bill .my machine had 2 inspection stickes on the top , I am guessing one was from the inspector that checks to see if it was painted green and the second to see if the spelling of Everlast was right , I know it was not from pluging the thing in at the factory before they boxed it up . Anyway enough rant and hope this one lasts a few yrs as at $556 out the door you just throw it in the ditch because you cant afford to ship it back from this country and as of yetvno dealers here , though I did mention it to my gas suppliers
