Testing need help with results
Posted: Sat Oct 10, 2020 2:27 pm
6090 Chinese laser still not functioning "normal" after replacing power supply with LO Smartbean 80W PWM CO2 Laser Power Supply. Reviewed all wiring and seems to be fine but did a number of tests but the power requirement seems to be at least double to what my past tube required - I replaced Reci with a SPT. I am not particularly fond of the connectors for the SPT - just a pole out of the tube, compared to other tubes I have had. I checked with LO Support and they said use alligator clips - I am concerned about arching. Anyway back to the tests (see below) There does not seem to be a good solid beam until I hit a power of 40, which in the past I rarely used any setting above 40 for anything - I would normally adjust the speed down rather than the power up, but now I have to adjust the power very high and the speed very slow just to cut through a piece of cloth?
Changed setting on multimeter to read above 20a - and when doing the sets at 50 % power it read 20 - 21ma constant
BTW - I used an external meter instead of the one installed on machine as it is not reading properly at all - any time I run a test it says EFE
Any help?
