Answer to 1) Yes, 2) Not clear from the pic but if you follow (WITH THE MAINS DISCONNECTED !!!) the thick (solid) three wires that come OUT of the main (BIG) transformer two should go to the areas that you have numbered and one will go to what looks like another large transformer but this is an inductor and will have the one wire going in and the wire coming out will connect to your ground clamp. If you use the ground clamp and clamp one of your meter leads, then set meter to AC Volts (up to say 50, depending what you have on your meter) Now power on welder, set it to highest power level and put the meters other probe on one of the two (of three) wires coming out of transformer mentioned above (may connect on 1 or 2 in your pic) Note you must put the probe on end of wire where eyelet is as the rest of the wire will have an insulating coating on it. Note down the reading you get when trigger pulled. You should see on meter aprox 12 to 15 volts AC. Now do same of other wire of the two (still keeping the first probe on the ground clamp) and again you should get 12 to 15 volts AC. If you then take probe off clamp and meter across the two wires that you got the 12 to 15 from you should see double this voltage.
This machine has a center tapped transformer hence the need to check two output.
