      Looks like common pump and now you can keep coolant in it I'm sure. 4AWG for leads will carry 1/8" electrode alright but they will get warm to the touch. With that machine and it's capability, I'd go with 1AWG wire which is still a bit light but would work fine.
      Thanks for reading/listening.

        Im welding like a champ!! Only thing is I have to run without rad cap cause it runs cooler, use a broom stick to throttle down. Other than that I'm on cloud nine.

          The word on these motors is they dont like pressure in the cooling system so I'm going to try to keep it that way. Reading about guys blowing head gaskets. Although this is the industrial version prob has some upgrades internally.

            Nice to hear you have it running/operating. Good feeling I'm sure.

            Mine has a zero pressure cap also. Think I ordered six of them from a single vendor on ebay for about $8.00 each.

              Remember the vendors ID? Been using a length of radiator hose around the neck and Pepsi can for a radiator cap for about 40 years now.

                Yes I do. www.reliableaftermarketparts.com

                I caught the caps on sale as they fit both the radiator and fuel tanks for all my engine drives. Look for them on ebay as it's cheaper to purchase there than their website believe it or not. I even called them direct and they told me to purchase via ebay.

                    If you need measurements of the caps I ordered let me know.

                        Most of it and have done a couple of jobs. Still have a ways to go yet but only purchase new when absolutely necessary. Going to retire early next month from the full time employer to strike out on the different path as a hobby.

                        This page will give you options also. http://www.fillernecksupply.com/3-or...er-necks-caps/ I used their filler neck to replace the one on my G-258 as it was coupled with a rubber hose and corroded badly. The cap shown will work also but has a small vent hole in the top. The Hobarts used the same size radiator and fuel tank caps on the older machines.
