do it at 90 with an oil cooled stick welderMIG, TIG, or MMA will all do the job, and you will need at least 160amp.
90 to 120 amp depending on rods usedMany thanks for your reply you say do it at 90 do you mean 90 amps ? Sorry if I seem thick but I haven`t much of a clue about this . Gordon . P.S. I intend to try to find night classes before I even buy the welder
