Thread: Lightning MTS 225 question about Power set

  1. Default Lightning MTS 225 question about Power set

    So I got my Lighting MTS 225 a few weeks ago... I bought a Lincoln Tombstone welder 40 tears ago when I was 15, I was never a great welder.... Now I know why, it was the machine not me. This MTS welds beautifully. Thanks to YouTube University I am learning to TIG and MIG.

    Now to my question, I have been Tig welding using the power set function. I was getting a divot at the end of my weld. After some research I learned that I needed to back off the power more at the end of the weld. However, it seems as though while in power set mode I was not really getting variation in power based on how far I pushed the pedal. So I put it into manual mode and have plenty of variable power. Why is that? Do I need to set the ramp up and down?

    It is likely you have some setting off in the manual setting portion as it still needs to be set with items like Pre/post flow start/end amps etc. And that you are on pedal only, not pedal 2t or pedal 4t or any other combination your machine program version will allow.
