I have nothing good to say about them. I bought a unit, within a few minutes of welding time, the parameters changed and the amps went to zero. Couldn't even hold an arc. Sent it back and they said it was defective and sent me a new machine. Within a few minutes of welding time, the exact same result. Sent it back again and this time they said it was a user error. Here is video of me trying to strike an arc with machine turned up to full power: ESAB Rebel FAIL - YouTube They refunded my money, I bought a red machine and couldn't be happier.
