I ran some beads for the first time in my life ! sweet! okay play times over , get to work. my floor boards have a couple spots. so I tried to stitch a panel . not bad a couple burn through s ,lol. 240volt170 amp mig. OK the guide says to go lowest voltage (min 1) 2 on the wire speed. I noticed if I push the gun into my weld it doesnt blow through. Im thinking it needs more wire so I turn up the wire speed, better. short bursts. By mistake I realize if I leave the wire longer (as in stick out ) it welds easier too ! oh by the way Im using .30 flux core wire, I would love to use gas but I dont have the money right now, lol. do you guys run a faster wire speed than what they recommend as well ?Im still pretty excited !! Im a welder now , a crappy one but still ! lolLast edited by yehaadon; 04-02-2013 at 02:24 PM.Reason: clarification
Reply:To a point longer stick out makes the weld colder. Too long and the wire will melt without making a weld.I don't usually run the wire speed faster than the door chart, sometimes slower. Your welder may like the faster speed. You may find that you have too much tension on the wire spool or wire feed. Too much on the spool and the wire may slip in the feed roll. Too much tension on the feed roll and you may actually slow the motor. It is best to have the spool tension just enough to prevent over run when you stop, and tension on the feed roll just enough that the wire doesn't slip when feeding a loop of wire against a piece of wood for a test.Smaller wire diameter and solid core wire make thin sheet metal go a little easier. For me 0.024 inch solid wire with C25 shielding is the way to go here.
Reply:thanks , I will check the tension. I checked into a 4 ft bottle today, I can lease one for 160 dollars, 204 filled out the door. I think Im gonna grab one. I found I can fill some gaps by concentrating my weld on the leading edge, and the weld bead grows right along. lol. |
