I stand corrected. I pulled out the manual for the Millermatic 252 today, and looked at the volt/amp curves, and OCV does not match setpoint voltage below about 50A, or basically while not welding. Our ancient Lincoln CV305 transformer machine does seem to match OCV to the setpoint whether it's loa...

Get a better helmet. I don't think you can see the puddle, or the "line" that you're supposed to be following from the weld joint. yeah I brought a new auto dimming helmet and was messing settings in the beginning of the night those pics where taken. Thanks for the friendly advice. Sent f...

sacman, set voltage to B. Then take a gun in one hand, another hand shall grab the wire speed control knob. Grab piece of scrap metal, thick one preferred. Begin to weld one handed and adjust your wire speed with another hand. If it is too slow you gonna see slow large droplets of metal falling, if...

Here is my machine that I'm using. According the website they made several different models "weld pak 100" hd and plus. They all seem to be the same,just wondering is all. Thanks guys for all your useful help and knowledge it's appreciated. https://uploads.tapatalk-cdn.com/20170429/2bbe684...

That seems very high for operating voltage. Probably normal for OCV though. Out of curiosity, because I don't know lol. Do you think that it will change under a load? Sent from my iPad using Tapatalk It should not change more than millivolts, since you have a "constant voltage" source for...

Your OCV will be DC, and will range from 15V to 30V, or even more depending on the machine. If you have a 50V scale on your voltmeter, I'd start there. Steve S Ok Steve, I did what ya said to do. Set voltmeter @ dcv200 and went thru each setting. With one lead on wire feeder electrode and the other...

Will do, thanks for the advice and your help. Gonna try and get it done asap and report back. Chris

Sacman, What you're looking for on the voltage side is OCV, or "open circuit voltage", which is easy to determine with a voltmeter. At the wire feeder, you'll see the post connected to the feeder for electrode contact, and the ground (workpiece) connection. Ideally, you'll connect your vo...

They're actually quite good for their intended use. For home shop/hobbyist welding they're perfectly fine, and you can cover a lot of ground with it. I firmly believe that good technique trumps all. Once you get some time on the metal with it and develop the techniques- no one will be able to look ...

That does help to know its maximum capabilities. By measuring outputs though, you can find the machines "sweet spots" for different types of welds and wire sizes. For uphill, being able to hit it at like 18.5 volts and between 220-230 ipm. or stainless at X volts and Y ipm, etc. It's also...

I found this in the operators manual I hope this helps a little. I tried the wire speed measuring . I'm not sure if I'm doing it right, but I rolled the wire back so it was flush with the tip. I went to lowest setting with was 1 held for 6 seconds and came out to be just about 5 inches. Thanks Chris...

If you have a volt meter that would be helpful too. You can measure your volts to have what they actually are. I would write all of this in the door of your machine. If you have all this info, you can accurately use somethin like the miller weld calcualator or we can help you more because your mach...

Almost looks like you need to increase your wire feed speed. Have you calculated your feed rate? well nope, wasn't thinking about it. Thanks!!! I thought I had it saved, no dice. Where I can find it on website? first started out today I adjusted according to the inside cover of the machine. Sent fr...

It been a while since I've been on here. I'm a beginner and haven't had much time to practice with the Lincoln weld pak 100 that was given to me. I put some time in today and was wondering how these welds look on 3/16 angle using 0.35 flux core. Also how do I know if there is good penetration? What ...

I got thru all the mig videos, awesome! Lots of info!!! Now to get cracking lol. I'm sure I'll go back to them for reference. I'm hoping to get some pics up asap to be critiqued, thanks.

It is an older regulator. Think there may be an Allen screw in the middle of the back of the regulator for adjustment. If not then I would recommend a new one. After a while the springs can get weak inside or the diaphram may be getting brittle.it may even have cracks or holes. Either way that styl...

Here is the regulator I have, It seems to look dated. What do you guys think? I'm not too sure,Thanks.

if you have the set up already and it has a good regulator.. i personly have gotten away with 10-12 CFH inside. as far as filling it up being as you have a bottle (provided they will fill it for you) u should be able to get prices from a local welding suppler.. keep in mind they may not refill the ...

The weld pac 100 is my first machine and I still have it. I recently bought a Hobart 210 MVP but I'm going to keep the little Lincoln and dedicate it to .023 wire and C25 for sheet metal and the Hobart will be dedicated to C02 and heavier wire. I bought the Lincoln in 98 and it has held up quite we...

20161204_125106.jpg I was given this same machine, I wasn't sure if it was a good machine. I'm new to welding and learning with it. Hoping to get some pics up soon of my progress to get some opinions etc.. Did you only use flux core while using this machine? Have you ever use gas with regular wire ...

There's a part 2 and 3 as well.

Thanks guys, I've watched the first one so far. Looking forward to the others,thanks for the link.

I totally new to welding, with little to no experience. I've always been interested in welding, but never acted on it. A friend of mine gave me a Lincoln mig weld pak 100 with shielding gas bottle. I'm looking forward to learning with it and using it to hopefully build some stuff for my truck. Betwe...
