I'm using .025 wire (i mainly use this machine for sheet metal) with C25 gas.  This was a fillet on 1/8th inch steel.  What do you guys think.  What could I do to improve?  I was on the highest heat setting my welder would go to.
Reply:bead is convex, toes dont look like they melted in well..seems like each dime started cold and got better.. break it apart to see ...
Reply:i used to get concave beads when i was just using flux core wire, how can i get the same thing with gas?  Do i need larger diameter wire?
Reply:I can't see the pic at the moment (dang computer), but I do remember that the 3200HD is NOT rated to do 1/8 inch steel with solid 0.025 wire and C25.  The more powerful SP175 (240V machine) is not rated to do 1/8 inch steel using 0.025 wire and C25!The door chart and the manual both indicate a max of 14 gauge steel using C25 with either 0.025 or 0.030 wire for the 3200HD machine.  The machine just doesn't have the 'snot' to GMAW some 1/8 inch steel, especially using 0.025 wire.The door  chart and the manual both indicate that using FCAW NR-211-MP 0.035 wire on 1/8 inch steel is within the machine's capabilities.From what I remember the last time I used my 3200HD, that's about right regarding the capabilities.  GMAW stopped being acceptable at 'gauge' thickness' steel pieces and FCAW could handle 1/8 inch steel OK.Troubleshooting:ropy, convex bead : Increase voltage, decrease WFS, decrease stickout, decrease travel speed, decrease drag angle (in that order of importance)Which is all in the manual dude!  RTFM    The best laid schemes ...
