I have the older version of that welder and its been very good to me. Perfect for exhaust work with a bottle. Been tempted to set it up for stainless lately.
I have only been able to try it with flux core so far, as I can't seen to get to the welding supply store during business hours. I have been pleased so far. Looking forward to less clean up on my welds. Prior to this, I have only had stick welders
