Lincoln welder

DC is best for mild steel, carbon and stainless. You only definitely need AC for aluminium.

As mentioned DC welding is good for penetration and starts the arc beautifully

I have the PTO version and it is a great welder for the big jobs. Burning a 4mm rod into one inch steel on 200 makes a 40hp tractor work. Mine has a 240 volt outlet as well but the neighbours older one has 32 volt power.

The Lincoln SAE S.A.E. 200 amp portable welder, along with it's bigger cousin, the 300 amp were popular for pipeline work and repair welding. Up here most have the Continental 4 or 6 cylinder flat-head gas engine. Some were made with a diesel engine but they are not common. 7018 is a very popular DC rod and in all the years I used a 200 for heavy equipment repair, that's all I used. The 'Shop Floor Talk' forum could help you out with any questions also.

I've never heard of that engine you refer to, but I believe the Hercules was used on the very early models. The vacuum idler is very temperamental and in 1972 the unit was updated with an electronic idler. There is a company in the U.S. that sells conversions for both the idler and the magneto, and supports restoration of these. They had a very stable arc and were very popular. Phil
