Will this machine even do AC stick? When I set it on stick the polarity control does not work. When stick welding It seems to be in DC and I can change polarity by switching ports but nothing tells me that. I am just going by how the weld is. I have no real need for AC stick welding but I have never seen an AC,Dc machine that would not weld in AC stick mode. I also had a different sensation when welding like the current was going up and down. When I looked in the book it says something about making sure pulse amp control is rolled all the way down. I have not tried it again after checking the pulse amps but I thought you had to turn the pulse feature on for it to work.
