what are you doing man I was working on the skin here on the wherever you go and i wanted to just clean up my little edges here my joints here where i'm gonna weld cuz i've got a little gap in here that I have to fill because I didn't cut it quite right I didn't fit it exactly right so this is where the pulse control on that longevity MIG weld 250 comes in so I can set the pulse so I can come in here to work in this you know gap that's just a little too big and I'm not gonna blow through hopefully and I can fill that weld in or to fill that gap in and then come back with my grinder and just smooth enough what can the pulse do that that you couldn't just do with the regular MIG welder well the pulse is just that that it takes the welding arc and it turns it on turns it off turns it on turns it up really really fast and what it does is it allows you to have the the right voltage so you've got the right heat you've got the right penetration going on but it only does it for a fraction of a second instead of continuously so you can kind of control the temperature a little better if you will you know you still get penetration but then it shuts off and it cools for it for a millionth of a second or so and it turns back on kind of shuts back off it turns back on that's what the pulse is for it and you can adjust that infinitely over there not not only the frequency of the pulse how many times per second it pulses but also the width of the pulse how long is it off or on you can adjust all that over there so you still have the right voltage you still have the right wire feed you still have the right penetration but you don't burn through is bad you know you don't blow a big hole because it got too hot because you were just probably oh that's what the office so let me just flip the switch here as I turn it on so you can see the see the settings you can wake up so you see it's about it's about 17.8 bolts and turn that down just a little bit with the pulse voltage turn it down to about 17 I got 2:12 on the wire feed my frequency is set pretty high I want that pulsar my final thought upon it and I wanted to come along an awful lot I don't want it to just you know like once a second I want in a whole bunch of times the pulse-width i have turned way down and of course when you change the pulse-width you change the voltage so we'll try that pulse-width is down in about three and a half holes frequency is up at eight the voltage is at 17 and wire feed is at 212 so why didn't you turn down the whip don't you want to have it as much wire feed as possible no no that's why your feet the width the pulse-width how for how many millionths of a second is the pulse on or off you can adjust that so you can have a long pause or a short pause you can get more pulses in per second or you can get you know a wider gap between pulses in you got to play with it really that to get it all in your head you know this is we're doing it gives you a lot of experience this is also where going to class helps where you've got a professional standing there who does this for a living who can say okay yeah he you know he kind of knows what he's talking about but this is the real deal if you really want to learn this right take a class that's what they're there for so grab your helmet and we'll play with this a little and make some sparks I see that actually worked pretty good good just the settings that I had on there for the pulse and the voltage and I could fill in that big gap but without having to sit there and you know in bubblegum it it didn't burn through or anything so let me let me change the pulse just a little let me slow the pulse down so I have less pulses per second and I might bump the voltage just a little bit and then I'll run down this seam right here we can still that guy into hang on let me change that what are you changing it to cap well okay well I left the pulse-width where it was and I turned the pulse frequency down to about three and I bumped the voltage up from 17 up to about 17 point eight just give it a little more heat because I've got less of a gap I've got that piece of 8-inch plate right underneath there so it can take some of the heat and then I can get a nice fill I can get a nice bead in there and I shouldn't have any problems not too bad actually huh my turn the voltage up just a little bit more give it a little more heat and I can go ahead and do the rest of these and keep working well sure because it's a little cooler because it's got you know the pulse is turned down just a little I can come in here and run a nice long bead all the way down through and come back and get the next one and run all the way through just make sure you don't lean up against it to reach across that gets painful but this is why you have all the different controls this is why you have the ability to set your different functions the way you want them to adapt to the changing situation anyways well let me get back to work here and I'll see you guys later
