This one is water cooled also, i owned it for about 20 years.. before the current owner had it.. (i didnt have pin striping though, a bit jealous).. Anyway.. the thing is a monster.. TIG or Stick.. i personally only cranked it all the way up only one time using 1/4" rods and it shook the floor and is just a monster.. and can be turned down for super fine tig work also. amazing machine.
P.S. whoever buys this... bring a cherry picker. it seriously weighs well over 500#
