I know its a heated debate on whats better push or pull MIG. I was taught pull and thats what I use unless for some reason I cant physically pull. I was taught to build up bead with MIG angle the torch back into the bead so it doesnt gouge as much and is pushed onto itself to build up. This works well for me my problem is I cant think of how one would angle the torch to build up bead on push MIG. I have never tried I guess I should but I havent cause I cant visualize how it would be done.Any thoughts? Hope this hasent been discussed. ThanksMaybe a step motion???
Reply:push mig(7 deg angle tourch angle) is the only way you can mig alu has a better cleaning action and better penetration as for steel same thing just works better thats my 2 cents
Reply:With push I just watch the puddle and move when the puddle reaches where I want it to be. I'm usually watching the top and bottom of the puddle to see when it fills in what I want. With fillet welds I use just a bit of motion to wash the puddle up and down between the between the vertical and horizontal pieces, I move when the puddle catches up to where I want it to be.Getting guys to see and read the puddle is one of the hardest things to teach them when I help with classes. Usually I run a giant exagerated weave ( usually a fillet weld) while I tell them to watch the puddle not the arc, so they can see what I'm talking about. I tell them to watch the top and bottom closely and see if they can spot when the puddle catches up to the arc and I swing the arc back in the other direction. If they can't "see" and read the puddle, they usually have a very difficult time doing verticals and overhead. It's easier to show than explain I'm afraid. Once you "see" this you will have one of those "AH HA!!!" moments and it will all make sense..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear. Actually, a government bureau is the nearest thing to eternal life we'll ever see on this earth! Ronald Reagan

Reply:Originally Posted by SkeluhtorThat makes sense although I have to say it must be alot harder to watch a puddle with the gun in the way. I guess after your get the bead going you can just do repetative motions so the feel plays a bigger part.
Reply:I see what your saying I totally didnt think about looking back at the gun. I will have to give this a shot and see how it feels. Thanks |
