The MM252 has digital read outs that a chart instructs me to set the machine to- might as well be letters too.īoth from leading manufacturers of welding equipment. The little Passport Plus has letters on the dial too. If you think you're influencing here with that kind of sense you're not.My Lincoln SP135 had letters on it You knock things twice already by guessing obsessively. It doesn't change unless you're a total noob flying all over the place which I'm not. Stick out on a flux core can accurately be measured at 3/8 or 1/2 with the same reading. This is backwards from proper setting technique where the WFS is chosen first (to determine amps) and then volts are dialed until it runs right. This will be the max possible amperage output for that machine using that specific wire. Happy testing, maybe you'll find useful data.ītw, to find max amps for a small machine, set voltage to max and dial wire feed speed until it runs properly. I find a more useful test to be finding out which settings I like for different thicknesses (if different from the door chart). I theorize that a low end inverter may be the same. This is my experience based on transformer driven machines. Unless you use a higher end machine that can control for changes, the tests are not repeatable in different locations under different conditions. Input voltage and voltage drop using different extension cords will also change the numbers. The numbers will fluctuate based on user repeatability. I've done some as well on various machines.īut that's really all it is, curiosity. ![]() If you think you're influencing here with that kind of sense you're not.Ī lot of people do these kind of tests to satisfy curiosity. And that's what im doing here.Īlso if you're trying to teach me I think you're missing the point. Volts, Amps and Wire speed for metals and thickness IS. Christ, if you don't like this test then bounce! Plenty more who want this info than those who think guessing is ok for finished welds. Have you no understanding of welding parameters? If that's obsession then let's all throw away science and guess china alphabet soup. The Titanium should be a little easier to setup the proper way so people (including myself) don't guess what voltage a weld and wire speed should be on a given metal and thickness. Welding is based on metal/thickness and the known volts/amps/wire speed to achieve a weld. I'll be welding with Lincoln Electric Innershield. Testing will begin this Tuesday 27th as weather is warming to 60° with low humidity. I know clamps can jump around about 4 to 6 volts (sometimes way more) and since there's already minor voltage drops at the arc (compared to the positive lead), I want this test to be as accurate as possible. ![]() I dont want to use the clamp side if its not nailing down volts and amps. Im going to test using the test leads and then the clamp meter to compare accuracy. Any other better brand was in the high $200 and $300 range that did the same thing. This model was $112.56 at harbor freight after tax. Turns out I had to buy this meter in any case because no other test meter reads DC and Volts within the Titanium 125s volts & amps (out of home depot, lowes, harbor freight options around $100 bucks). ![]() Bought a AMES 1000Amp AC/DC (6000 counts T-RMS INRUSH) clamp meter that also lets you use - and + contact leads for direct contact which is my preferred testing method.
