I'm building my CNC plasma ,I have Masso G2 controller ,and Hypertherm powermax 65A, plasma source,and Proma THC . I used Separate power supply 24vdc to THC .

I connect wiring as per Ross Wiring diagram I used ,I do g code in seetcam .

Torch is triggered with masso arc is coming , when I do cycle start , plasma torch goes up during cutting time ,Torch not stay to closer to metal . Why would it start rising after it starts cutting? I have the THC setting on default

Please help me

Thanks @ross I'm at the stage of my retrofit now where I'm about to get a THC. I'm guessing the Proma is still the one to go for at the moment? How do the settings change for thicker plate? I'll be cutting 10-20mm

With out going through any of the settings, when you first press the up or down arrows it changes the voltage.

I cut 2mm at 40 amps to 10mm at 60 amps, It is nearly a set and forget once set up.

As the consumable wears you just up the volts as needed. this can be noticed after each touch off, that is if it is to close to the plate.

Still happy with the Proma and and i haven't had a problem with crashing at all.

Cheers from Ross.

has any one used the mini THC unit www.minithc.com i used them on other controllers i used the proma and the robot 3t . out of them all i like the mini

they also have ohmic and switch inputs to use boath . and anidive settings .and a thc delay .. plus with the knob you can change voltage on the fly . so if you see your Z dro running to high lower voltage .

just some input

Derek, I tried to do a coupon but no luck, i am buying things at the moment as well.

OK, Provided your sheet is perfectly level and doesn't slope in any way.

What happens is it does a touch off 3 mm height for pierce then down to 1.5 mm for cutting, then the Proma kicks in and will keep the height close to what you set it at.

Eg Lets say it starts at say 1.2 mm < 2.2 mm when cutting and then after a while 17 minutes or so it will read 0.4 mm < 1.4 mm in Z height on the Masso screen, you know the tip is burning away so go back to the Proma and press the up button a few times, go back to the Masso and check how the height is reading and adjust the Proma some more if needed.

I all ways check the Z height at the start of each cut to see how things are going!

Hope this helps.

Jeff, I didn't get back to you on YouTube, But hopefully Peter can solve the requests for you.

It looks like Peter answered the feed rate for you but i have never tried it myself.

THC inputs is there a setting to slow reaction speed? SheetCam post processor has a feed rate built into it and can be edited.

--THC on and off codes. Use nil if you don't want THC control e.g:
-- thcOnCode = " M667 F130"
-- thcOffCode = " M666"

--here is another example that use M667 and M666
thcOnCode = " M667 F130"
thcOffCode = " M666"

I have the Masso G2
