[Amps] MW Oven Transformer question

[Tony King - W4ZT]

John,

The MOT I used in my tester (<http://tester.gs35b.com>) has welds across 
the laminations in four different locations. The transformer gets pretty 
hot with no load (shunts removed). Fortunately, my duty cycle on the 
tester is very low so it really doesn't matter for this application. The 
four lines of weld is why I asked the question.

73, Tony W4ZT
