8/14/2023 0 Comments Amp to volt ratioHey Buddy, I'm not going to change the world on you but I don't see it mentioned so I'm going to mention it. He Is In Control, Have a Great Day, Brent So much easier than using a volt/amp meter with no one to help read while welding. Pull the trigger, let it run for 10 seconds, measure the wire length that came out, multiply by 6 and you have you inches per minute (ipm) to know your wire feed speed (WFS). It is a fast and accurate and consistent way to monitor current control. I almost always go by the wire feed speed. I seldom get at all concerned about amps. Bottom line, you are not 'converting' volts to amps to know what you are running. The more volts you run the more WFS you will need to get a good burn off rate). The amps are relational to the volt and wire feed speed setting (really proportionate to WFS but also directly related to volts. Now, most often you are best off to set your volts to the recommended setting then adjust wire feed speed to get it to run within manufacturer's specs and where it works best for the application. Mine has a voltmeter and a WFS/amp meter. 035 is the max recommended for that power supply.045 can be done at sometimes but it is just too big a conductor for the power supply design and the results may not be satisfactory.ĭon't remember if mine is the 252 or 251 but I use Millers. The machine is not heavy duty! You did not mention filler dia. Edit: Your operators manual for the 252 does not give WFS recommendations for. The only time you want to push is vertical-up or when purposefully trying to reduce penetration, and it still may cause problems. If you are running a push this could cause worm tracks and problems. Gas Shielded FCAW should be run with a drag (backhand) gun angle of 10-20 degrees. But it is an example how you can put the information provided here together to come up with WFS and Voltage rates that will serve you. Your FCAW Manufacturers data may be close to this. Second attachment is from a data sheet for ChromaWeld 308LT1 by McKay. You said you were welding stainless (thin) is your FCAW filler also stainless? This can have a bearing as stainless fillers do not behave the same as carbon steel FCAW fillers. Do not change unless the manufacturers specifications allow for more than one gas or combinations. The 252 owners manual gives calculations (attached) that can put you in an actual ballpark (with a typical stickout) If your FCAW filler calls for 75/25 use it and nothing else. Typically as the weld is being placed the readout for WFS will convert to live amps, so that a bystander can see what is actually happening. Shame on Miller for not giving you a live amperage (current) reading on your digital. Knowing the amperage for a given wire feed speed is important, good discussion has been given to electrode extension (stickout) and how it effects the arc energy and weld profile. Let me try to help you where the rubber meets the road.
