Fiber CW vs QCW mode

[laserarts]

Hi guys,

I have recently got chinese 500W fiber laser with IPG source. The source has continuous and quasi modes. I only cut in CW mode with good success.
Can anybody explain why would I use QCW(pulsing) mode?

Thanks in advance

generally pulsing is used to reduce heat on your thicker materials, small profiles, corners. and your lead in, so you would only really need it if you were pushing the machines material thickness limits. or cutting very small detailed parts were heating was an issue

Thanks Chalked. Unfortunately there's no way to switch on the fly, say pierce then cut. I have to select the mode prior to cutting. Would pulsing mode change the gas consumption?

 

[Chalked]

in general. yes it will. but not because the laser is asking for more gas. but because generally pulse cutting is done at a slower rate then continuous, there fore the beam is on longer. I can't speak to the specifics of your machine but the consumption difference for your machine would probably be unnoticeable.

Which machine did you get ?
