I use to use welding bond kits for these larger connections. Also use to do infra-red pictures to give to my customers free. Camera was not a high dollar one but would help. I educated customers about the importance to have it done on thier entire building once atleast every 5 years. Showed them how to get discounts on thier insurance by having it done

Thanks for making these videos. I enjoy your abilities to relay information to everyone.

You could check the bridge rectifier and IGBT reverse bias diode check of the inverter board by using the 12 point checks

Best video covering vfds that I have found, great breakdown!

finally a video about vfds.

Gracias por El tiempo y la clase bro. Muy Bien explicado. Saludos desde Houston tx

Great teaching skills

Thank you for this awesome video

It's more than just being true RMS DMM. The DMM needs to have a low pass filter so it sees the RMS voltage without seeing the invidual PWM pulses.

Oh yeah

Looking for day 2 video thx

RMS =. 707 x voltage peak Average = .637 x voltage peak

True RMS.....Root Mean Square...
