If I only knew then what I know now. It seems like a couple of years ago when I first started asking for advice on equipment someone suggested the push pull setup but I had never used one. I bought a sync 250 and a spoolgun for my MM210 instead. Yesterday I had the opportunity to use a 350 W/pulse. Very impressive. In my first attempt at using it I laid some of the nicest beads I've ever done. The difference is the pulse feature. I also loved being able to change wire speed at the gun. If your about to spend big bucks on a machine I don't think you can go wrong. Anybody had any bad experience's with this machine? I've got to get one. ADAM
