NICE.

Mind I ask what the entire setup set you back?
Couple things....
Power change is on the back right, lower corner if facing machine, just have to move the jumper. Take off top cover then right panel. While you have it open to change the jumper, blow the entire machine out and check everything over.
Check and adjust the HF gaps if necessary, front under flip up pannel.
I'm not sure what vintage your Watermate cooler is, but be careful, the older ones had a orberdorfer gear pump that was prone to failuer if non proper coolant was used. They are also very $$ to rebuild and are better to be replaced by a special Procon unit. BTDTNA.
Looks like a more modern foot pedal. The older metals ones are just a classic.
Post up the two first letters of the serial number and I can track the year made. I have a 91 IIRC. Enjoy that machine, it is probably the last tig machine you will ever need.
