What is a good welder for a novice? Perhaps arc welder, or mig welder?
‘Cisco– asked:
I’m trying to learn how to weld, and I haven’t the slightest idea on what would be a good starting point. I don’t know any good welder manufacturers. The project I’m trying to build is a standard-type server rack, about 6-7 feet high. I want to keep it enclosed so I can properly filter dust, and keep the systems in the rack nice and cool. Any suggestions?

Why is the input and output wattage of a welder different?
Brad asked:
For instance a welder can have a 200 amp output at 18 volts, but has an input at 20 amps and 240 volts, making wattage input 4800 and output 3600. What explains that loss in wattage?
Obviously these numbers are absolutes. However, if you physically measure the amps and volts at input and output, these are actual/real numbers. In this case you aren’t consuming more energy than you are creating, there is a 1200 watt loss. Where does the loss occurr?
