Convert Pulsed Parameters

[Germanmachinist]

Hi Folks,

i have a little Problem with „converting“ Pulse Parameters for Tig.

For example, given Parameters are:
- 1.4 Pulses per Second
- 45% Peak ON Time

My Machine is not capable to set the Parameters this way, i can only set Pulse High Time and Puls Low Time per seconds. Like that:

- Pulse High Time 0.24 seconds
- Pulse Low Time 0.38 seconds

so it is possible to set it accurately at 0.01 seconds.

How do i Convert the upper mentioned settings to my machine?

Kind regards,
Christian

What machine do you have?

might be a case of someone here having the same machine and the “right” settings

1,4 pps equals 1,4 Hz
Period, or cycle time is then 1/1,4
So your high pulse time is 0,45/1,4
Low pulse time is what's left of the period.

Clear?

So that means:
Cycle Time is 1/1,4=0,714 seconds

that would mean 45% Pulse ON would be:

0,714 Cycle Time x 0,45=0,321

so the Settings would be:
0,321 Cycle ON Time
0,393 Cycle OFF Time
Cycle total Time 0,321+0,393=0,714

I think i get it
