OK guys, got the above welder and it is a big machine. it is 220 and once plugged in it emits a low buzzing noise which I understand is normal and from something inside the machine. Once you turn the "on" switch on it works and welds just fine. My question is I assume this machine is using electricity 24/7 and I don't use the machine every day so it is costing me money when not in use. It is also a pia to get under my welding table and plug and unplug everytime I use it. So I'm wanting to put in a switch somewhere along the plug in line and mount it on the wall so that turning the machine on and off is more convenient. So in essence a inline switch on the power cord. What type of switch should I use.
