Lol I will not forget to buy a welding gun,

A humble brag but this is what a $17,000 robotic inverter welder looks like.

Attachment not found

And this is the latest welding gun I have brought,

Attachment not found

After around 10 years of welding everyday I decided to let machines do my welding.(Although I do miss it sometimes)

very professional welder,,,
the weld gun cost about 1100$
for cs6mm deep penetration u need 3kw

My brother is the professional welder in the family, he has his pressure welding tickets for welding pipe lines and such( He is his own robot). He has told me about the hand laser welding machines but we both have not use one.

Have you used such a welding unit? I image it would be for exotic metals like titanium and anything that would need a very small heat affected zone.

What is something like the above commonly used for?

i never use it my self but i ordered one and its in the way,,, its perfect for thin sheet metal fabrication and stainless steel welding..
also kitchen cabinet welding
also for multi sheet defusing together with spot welding,,,

consume less power small heat effected zone
the gun is heavy compare to welding torch

okey i found a sloution ,, that change capacitance to 0-10,,,

now need to cancel probing and relay on the reading from THCAD to determine the hight... it have similarity as flame cutter oxy

also ARC ok need to be ignored

this is the sensor if anyone need it

I'm not sure if plasmac is the right interface to start with. Except that is has Z axis height control. Why not just use a simple gui that supports X/Y interface and a much simplified version of plasmac.comp?

From what I understand, the capacitive sensor outputs a 0-10 volt scale to represent height

You could use a modified version of master branch ohmic.comp to output a probe signal at the desired height/voltage. Then you could use a simple gcode subroutine to probe to the surface and stop at the correct height. This is how most of us did plasma probing before plasmac.

So when at height, start cutting and hand the Z axis over to the plasmac component height control.

yes exactly that what i want,,, but plasmac offering pricing time and cutting height,,, more automated.. with paddle function for thick piercing .. where can i find the modifed ohmic.comp

also if i can modify the plasmac to add this,,, it will make it easier to work with,
i have full time programmer he can handle this,, if he get some guidance

ohmic documentation is here
linuxcnc.org/docs/devel/html/man/man9/ohmic.9.html

The source for both plasmac.comp and ohmic.comp live in git in this folder:
github.com/LinuxCNC/linuxcnc/tree/master/src/hal/components

You may also be able to modify the plasmac probing to do what I was thinking.

thanks alot,,, i will try it,,, and i will update

okey i have update,,
it seems all good,. except one thing,,
auto foucas motor inside the head is considered as 4th axis,,,and i should adjust it according to the cutting height and material thickness also cutting or piercing,, whats the best approach to fix that

You should be able to configure the focus motor as an axis if you think that will work best. That means that it would be controlled from inside C-code by an axis letter.

But, whether this is a good idea or not would depend on the source of the information used to control the motor.

I suspect that it would be better to control the motor inside HAL, independently of G-code commands. (in very nearly exactly the same way as torch height is controlled with a Plasma machine)
