Has Anyone Converted the Wire Feed "Numbers" Into Inches Per Second?

admin

Hey folk,  the only welder that I have here at the house at the moment is a Chicago Electric 90 Amp [it is what it is].  As you likely know, it has those numbers [0 thru 10] on the front panel for wire feed speed.  My question is: Has anyone mapped those front panel numbers to the approximate corresponding inches per minute [IPM] for this welder?  Example: #4 on the welder corresponds to 250 IPM, etc.Figured I'd ask here in order to save me the time of mapping it out myself (and wasting some wire in the process).Thanks.Last edited by MrGatsby; 05-02-2020 at 11:38 AM.
Reply:They may or may not be in equal increments. A simple way to measure wire speed is feed the wire for 10 seconds and measure it. Then multiply by 6 to get wire speed in inches per minute. You can buy a wire speed gauge but they are expensive. Usually you set your wire speed or volts and play with the other until you get the desired characteristics.

Reply:You don't have to waste wire, just relieve roller tension and wind it back on the spool then retension rollers and start next test.MikeOl' Stonebreaker  "Experience is the name everyone gives to their mistakes"Hobart G-213 portableMiller 175 migMiller thunderbolt ac/dc stick Victor O/A setupMakita chop saw
