Hello, I have the chance to buy myself a newer welder although 2nd hand, seems in really good condition. Not sure how many voltage settings this machine should have as standard, the course setting is not on the machine, holes have been blanked off, maybe this model come's like this from the factory ? Doesn't look wrong. It only has the fine adjustment and wire speed ? Is this correct on this model ? Oxford mig maker 180-1. Any info would be grateful. Thanks.
