That looks like a clarke welder, and with the deep discount, a discontinued one. You will pay more for the name, but get a miller or lincolin. The consumables for the off brands can be hard to come by. If you could change out the torch (not likely) for a standard (name brand) unit, it would cost more than the welder. If you can afford it get a 220v welder, so you have more than a 10% duty cycle.
