Dan, list,

Lest someone be running around looking for a "Lincoln 220AC", which does 
not exist, the two model
Lincoln arc welders that have worked well for me are:

AC-225C- moveable shunt current control, lighter duty and more compact.

AC-225-S-more heavy duty, tapped/switched current control, ~ twice the size 
of the 225C physically.
