I found the address in the guarantee, since my mig 140 machine broke down, they attended me quickly, and in short they changed the damaged card, they cleaned it, they made my invoice, and the machine continues to work, all in an hour or so , I will continue attending, I just bought another lincoln
They made the change of card for guarantee in the time they promised me. The machine is working fine. I recommend it even for gas newsrooms that I couldn't find from brands that are not very commercial.
