I use the Personalizer Plus. I bought my stencils from I M G. I also bought the knife makers pak of Solutions. I was instructed For marking to use electrolyte 94 for carbon steel. No problems there. Was told to use electrolyte 600 for marking stainless. I cannot get a nice dark Mark with it. I have Tried more power, more time, just can’t get a nice mark. What are you guys using?
