Question about the sMig function vs door chart on ESAB welders

admin

Hey guys,Just a quick question about the sMig function and could use some input. I recently got the 205 ac/dc machine and was playing around with the sMig mode and noticed the when adjusting for material thickness, the wirefeed speeds do not correlate to what you would use for manual mig mode. For example in the door chart, to weld 1/8 material using .030 solid wire it says to use a wirespeed feed of 300 and voltage at 19.5 when using manual mig. When using sMig, setting material thickness to 1/8 does not set wirefeed speed anywhere close to 300 (I think 1/8 comes up around a WFS of 260/270). Going to 300 causes it to go next higher material thickness (10 gauge in this case). This is before welding, just looking at the settings.I'm wondering if my machine is malfunctioning. Is this correct? One would expect the ranges in sMig to line up somewhat with the doorchart?Can anyone else confirm this is the same for their ESAB machine in sMig mode?Thanks for any help!
Reply:You can try to call ESAB tech support and ask them. Phone number is in the owners manual.

Reply:Door charts are a starting point.  In Smig the machine is suppose to compensate for all the variables you present to the machine including poor ground clamp and nozzle stick out.  Manual settings won’t compensate for poor conditions and or inexperienced welders which is the reason I went with the Rebel for my first wire welder.  Been happy with it for the most part.  I learned a lot by having it and what to look for in other machines now.  Change the variables while in Smig and see if the amps change.  As I understand it and as has been said many times by members here on ww, wire feed speed directly correlates to amperage.  Try changing your stickout and see if in Smig the amperage changes.  If so it is quite possible the machine adjust the wire feed speed to adjust the amps for material thickness settings but this is just a theory on my part.  ESAB can or should be able to shed more light on this subject.Last edited by N2 Welding; 12-19-2020 at 03:21 PM.Lincoln, ESAB, Thermal Dynamics, Victor, Miller, Dewalt, Makita, Kalamzoo.  Hand tools, power tools, welding and cutting tools.
