We all know the old SA welders are extremely popular. But Im curious as to if anyone has bought one of the new ones and how it is(compared to an old one) or in its own right. The new "classics" have all copper windings, but do they have as good of a "feel" as the old ones? And what about durability? Obviously they havent been around for 60 years to really prove it, but do people have issues with the new ones or are they trouble free? Interested to see if anyone even owns one.
