How do I set up the Miller Multimatic 200 for welding?

First, ensure the welder is unplugged and connect the appropriate power cord to a compatible 120 V or 230 V outlet. For MIG and TIG processes, connect the gas cylinder to the welder's gas inlet and set the regulator to the recommended flow rate. Install the appropriate electrode or wire, attach the ground clamp to a clean metal contact on the workpiece, then turn on the welder and select your desired welding process using the process selector.
