I just ordered the PA 160 STH yesterday and I am super excited about getting it. I have only welded with a Century AC 100 box and it has been painful to say the least. I am excited to start Tigging and running some DC current. I cannot wait to use it and review it on my youtube channel. I guess I should start a new welding channel since my current one is about Ironman training and events. I will do some keyword research to night...
