I have a d1pro 10w. While doing materials test in light burn. With my 1064 IR head attached I realized I accidentally still had the 10watt supply hooked up. So stopped it. Shut down and hooked up the IR 1064 power supply. Finished material test it barely touches the stainless.  However my 10 watt supply with ir1064 is looking a 100% better    Do I have a bad 1064 power supply?   Why would my 1064 work better with 10w pwr supply than the power supply that came with it and is meant for the 1064????
