I'm gonna drag this up....
The IRD were good to me so I went and splashed out on a AC/DC/pulse unit like that posted above, even got an owner bottle and a new helmet. Had 20min playing in the shed and man I am hooked, having so much control of the weld pool over what I am used to with MIG is incredible. Had a play on some panel steel and like how you can have such a small, concentrated pool with the pulse setting. I can safely say I'll only be using the MIG for quick and dirty jobs in the future and look forward to improving the skills
