How accurate is the chart on my Lincoln MIG?

admin

I've got my new Lincoln MIG 180C up and running (yippee), got my 75/25 bottle last night, going to give it a whirl now.Question though, how accurate is the chart they have pasted to the panel that covers the wire spool (that recommends the wire speed, etc., based on material thickness).Is this generally just a rule of thumb, can the settings be off by a mile, or can I depend on the settings for general purpose welding (mild steel).Regards to all.Working on cars and bikes is my hobby, learning to weld the pieces together is my quest.
Reply:It will get you in the ballpark.When I first got mine I used that chart a lot...but now I know about where I want it ,then go by sound.Just saying after a few spools you won't even need it anymore.
Reply:I found that the chart on my 216 was pretty close. I do tend to run a little hotter than it calls for though. I'm usually welding 1/4" or thicker though, so burn through is less of an issue than with thinner material.Andrew
Reply:Probably pretty close but each operator will have their own preference, some hotter than others.......There is a technique to be considered.....  Miller Dynasty 350Twenty Six HammersThree Crow BarsBig Rock
Reply:I have the Pro MIG 180 and often find myself turning the wire speed down a bit from the chart specs. The amps seem pretty close but I have gone one click up at times and that did not cause any burn through problems.Tom Hintz, publisherwww.newmetalworker.comLincoln Pro Mig 180Lincoln AC 255Determination
