How to Weld With a MIG Welder With Pulse Control – Kevin Caron

(Text on screen): How to Weld With a MIG Welder With Pulse Control, Kevin Caron, The Voice: Hey Kevin, what are you doing? Kevin Caron: Oh, we’ve been playing around with this Longevity MIG Weld 250P MIG welder. Got the bottle on, got the gas hooked up, got the wire in it. Looked at the controls; figured out how all the controls work. Now it’s time to fire it up. Let’s make some sparks. So, put on some leathers, put on a helmet, grab the gloves, flip the switch, let’s go to the table and play. So, I got some eighth-inch plate out of the scrap barrel out back. Cleaned it up a little with the grinder, cut of a little chunk; a couple of little chunks to play with. Because I’m just working with a piece of flat plate, I don’t have any place to put my ground clamp to. So, let’s just go ahead and clip it down to the table. That way I can ground on my table, get a nice ground through to my work, don’t have to mess with the clamp. As far as setting the machine, eighth-inch plate, we’ll start at about 19 amps and about 200 inches; 210 inches worth of wire feed. Somewhere right in that area. And see how it does; see what we get. The Voice: How about pulse? Are you going to use it? Kevin Caron: Well, now, this will just be straight MIG, so the pulse features are all zeroed out. So they’re not going to work. So, we’ll set our base voltage at, let’s say, 20 amps. And our wire feed. . . About 210. Let’s try it there. So, let me get my helmet. You get your helmet. And we’ll see what we get. Well, let’s just try a little corner joint over here and we’ll see what we get. (welding) Kevin Caron: See, that doesn’t look too bad in there. I might have gone a little too fast right in that area. Let’s flip it over. So, you look on the back. I had a little bit of metal coming through the gap where the two pieces didn’t fit quite as well as they should have. Yeah, should have gone to the anvil and flattened that out a little bit. That’s what you get for working with scrap. But not much in the way penetration. So, I was probably a little cold. Next time, bump it up a little: 21, 21 and a half. Somewhere up in that area. So, let’s go ahead and get a thinner piece of metal; find some 16-gauge out there, and then we’ll play with the pulse just a little bit and get another weld on it. I’ve got a little piece of 16-gauge. Same scrap bucket. So, let’s go ahead and just tack that; we’ll weld that on real quick and we’ll play with the pulse. So, like I said earlier, put your base voltage down. Put your pulse voltage up to what you want. That’ll enable the pulse feature. So, let’s go with. . . Turn the base voltage down to about, oh, 15 amps. Or 15 volts, rather. And we’ll turn the pulse voltage. . . up to about 17 and a half. Pulse width: ah, let’s set it in the middle. Pulse frequency: set that a little higher. Ah, let’s try that. The great thing about getting a new machine to play with: You get to play with all the knobs, figure out how everything works. So, let me just hold this in here. Got your helmet on? Cool. There we go. (welding) Kevin Caron: Nah, let’s change it just a little. Turn the pulse width up a little. Turn the pulse frequency up a little. And turn the voltage up just a little. Pulse voltage. Now, let’s see what we get. (welding) Kevin Caron: Oh, that’s fun. So, a little more with the wire feed. And let’s turn the pulse width up a little more. We’ll turn the pulse frequency up a little more. Nope. More wire. More wire. I’m going to find it there eventually. (welding) Kevin Caron: OK. Let me get one more piece. There’s another piece of 16-gauge. Same gauge stuff I was just welding on. Now let’s run a bead. (welding) Kevin Caron: Anyways, nice little bead across the front. Decent little welder. I like it. I really do. It’s a big improvement over that old Miller 251 I got. So, I’m looking forward to playing it, you know. And then learning all of its different features. Get a spool gun for it. I can use it on this big aluminum job that I’m working on. I think it will be a good addition to the shop. Now, let me get back to work. We’ll see you next time.

  1. Sometimes we don't need no stinking pulse…aaaaaaaaaaaand sometimes we do! Thanks guys. Good info, great presentation.

  2. I've been looking at the longevity welders for a long time as a replacement for my $100 harbor freight el cheapo. I've heard good things about them, a little loud, but I can live with that.

  3. @genghisman39 I hear that! Wish I didn't. In talking with Simon, the owner, he said that they are working on a retro fit for a thermostat for the fans. We should be able to just pop the cover and fix it ourselves. Not sure on the due date but they are listening….

    I really like this unit. Does a nice job and is easy on the wallet.

    Thanks for posting.

  4. @RCDriftChaser Heck, you are only 4 hours from Phoenix. Come on down for an over nighter. Spend a day with me and check out the nightlife here in Phoenix…

  5. @CBaughman Good point. I am still smarting over that butt stomping..

    I was just trying to add my 2 cents to the thread. Got jumped on for sure..

    Oh well, moving on……

  6. @mustie1 It's weird. I can hear it working but I can't see the pulse like with a TIG. Still getting used to how it works. Was doing some fab work in the studio today, making a cutting jig for this new piece. You will see the video soon……..

  7. @robotmotor Not sure, I have that problem sometimes myself. Maybe something to do with how clean the metal is or isn't. Maybe you are pushing the puddle instead of pulling.

    Anyone else got an Idea on this??

    I don't do a lot of stick so I really don't know…

  8. I remember reading somewhere once that the burnback is the amount of burn that can occur on the wire before the arc cuts out its to allow you to be left with more or less wire sticking from the end of your torch I would assume!

  9. @ragnarokzero1988 Sometimes my brain runs slower than my mouth. The gray hairs give me a pass on this one…..

  10. I weld using pulse and is going to or try to anyways, verti up certs. Im having issues with my root pass..
    Any advice??

  11. To be constructive, "this is not great" where in the video do you explain the difference between pulse and non pulse welding, you coud have showed your (not enough wire) welds so people can identify a low wire weld. This is not a how to, it just a video of you welding.
    Imagine a class of kids watching this, they would not be able to explain puse and non pulse welding.

  12. You do understand we are doing these videos because we want to, not because we are getting paid for them right?

    Sorry they are not up to your standards, I will have a firm talking to with the camera crew..

  13. its a shame to need ear-plugs on when turning up this machine, sounds like a airplane. prefer kemppi or esab

  14. I hear ya! That's the only thing I don't like about this machine. My old Miller was so quiet compared to this one. There is supposed to be a retro kit coming to add a thermostatically controlled fan. Hope it comes soon!!

  15. you can hear what needs adjusting. personally i would have reduced the pulse width a touch upped the frequency and played with the voltage and wire speed so its just right. sounded like you had too much pulse width, need to get a nice buzz going 🙂

  16. nice vid, like me, a kid with a new toy.
    ps. i don't get pulse welding unless its tig.. oh yea, i do structural and hvy fab so thats probably why. love to see some updates

  17. hi steph, run a vert up root pass, harder i know, but penetrationpersonall is important, not looks, use a grinder to take high points off if you wish.
    i personally go with a swing up motion on the root pass.
    the weave will burn out any problems, if you have good contol and speed

  18. I was asked to test the machine for a month. I found out I liked it better than my Miller. Did a better job at half the price. Replaced both of the Millers and the HyproTherm plasma with Longevity for about the same price as the two Millers that are 8 and 9 years old.

  19. pulse is just a "mode", there is short circuit and spray arc, but pulse just makes fabrication easier. I use pulse at my shop at my school for fabrication, and it really does make the vertical welds 10 times easier and faster to do. we use Lincoln C300's and there are over 200 mode settings on the machine, it's really fun to play around with.

  20. + Kevin Caron do you think the pulse feature is all that important for a hobbyist/ weekend warrior? I'm in the market for a mig and really like the look of the AHP Alpha MIG 250. I'm just getting started and want to get a super versatile machine .

  21. In my opinion your making it a little more complicated than it needs to be in messing with all the settings. Also alot of spatter. I like hearing a nice hum and a little sizzling like cooking bacon. It interesting to see how others weld, cool video.
