I have been using a sync 250 for years and I have just bought a Dynasty 200dx. With both machines the weld bead is shiney but looks as if there is "sand" embedded within the bead. Any thoughts as to why? I use 4043 filler and ceriated tungsten slightly to the more penitration side of balance... have tried more cleaning but no change.

There was a huge thread on this a while back on here about this with the dynasty machines. Try 5356 filler. I used this the other day on my accumulator tank I made with my dyn 300DX. It came out shiny(5356) and no grainy look or feel. Someone stated in the other post about how the inverter machines bring the silicone to the surface that cause the grainy look. I cannot find the thread on this, but do a search and you should be able to find it. It is on the Motorsports board, Ask Andy.

In code work at our shop I require the tip of the filler to be cut off with wire cutters and the filler rod to be cleaned with stainless steel wool. Oxidation sets in on aluminum is short order. Don
