    Summary of polarity and connections-maybe you already have this but if not .....please forgive me if this is redundant...
    Connect your torch to the ELECTRODE terminal. Connect your "ground clamp" to the WORK terminal. Select DC - (not DC+) on the polarity switch (which you have done). You should now be set to tig steel. You will be operating EN (Electrode Negative, or DC straight) polarity.

      In their day the washing machine sized "GREY" Lincoln IdealArc Tig-300/300 were a formidable piece of equip

      I put a lot of hours on them in the 1970's

        Well, Thanks to all who responded, I've done all as instructed and can't think of anything else I am missing. I am still eating up my torch rods and eating big holes in my work. Looks like I will be loading up the whole kitten-ta-boodle and taking it down to be looked into, serviced and repaired if needed. At least it will get a good cleaning, that being said if they can't find anything wrong with the machine then it has to be me, so I'll have to go back to school, it's a long drive to Missoula.

          Another Thought...... That this may be a magnetic amplifier machine.... if the mag amp power supply is off or fuse is blown....

          the machine will output full throttle for the range it is set... so the pedal will not work... so you will be burning up tungstens and blasting holes in your work

          if this is the scr version... you may have one or more blown scr's.... but it would behave the same way

          We need a schematic................

            Maybe you have a friend that is a little more experienced to come look at it before you pack it all up?

              I appreciate all the info guys. I'm going to take it to Missoula I believe the problem is beyond my ability.

              My wife and I are pretty reclusive, I don't have friends just acquaintances, works best for me. We live way up on a mountain all by ourselves, just our dogs to keep the bears out. No people just critters, we don't ask for help and do everything we can for ourselves if we can't do it we pay to have it done. We don't have a lot of money so we have to wait sometimes for quite awhile before we do something but it works for us.

              Thanks again to all that responded, we all did out best, it's just beyond me and long distance problem solving, again thanks

                      Well guys an update on my machine. I finally got it over to be looked at. I had them go all through it, had it cleaned and tested. The problem turned out to be very simple. I had holes in my argon gas line and wasn't getting any shielding gas. So bottom line, I got a new line and my machine was totally went through and cleaned up. I'm now welding and a happy camper. Should last me the rest of my life and whoever I pass it down to. Thanks to all who helped me along.

                        Guys, I've got the above welder and have a question regarding the two cables on the machine and exactly how to bolt them on. One is larger diameter than the other and goes to a large spring clamp that is attached to my welding table, Does that cable bolt on to bolt labeled "ELECTRODE" or to the bolt labeled "TO WORK". The other cable is narrower in diameter and goes to the torch "stinger", does it bolt to the bolt labeled "ELECTRODE" or to the bolt labeled "TO WORK"?
                        Stinger & TIG torch connect to ELECTRODE....

                        WORK is often called GROUND
