Weldorz. 1/16 6011 is bad to the bone for tacking the corners on 1x1 or 2 x 2 inch 16 ga. posts on 100-1000 feet of fence.(6010 in a proper DC) then ? Go after it with a good 6013 or 7014 in 3/32.Lean it over and pull fast. Stick like MIG as I call it....70-80 amps...straight pull.....blow the flux away from you
