Hi,
I need some help
Today i went crazy and bought a used max 100, that wasnt the crazy bit, the guy i got it from had it hard wired and had removed it so i couldnt see it running, he assured me it worked, the trusting soul i am i bought it, that was the crazy bit.
So i got it home and hooked it up, it switches on, the safety interlock works, the torch fires te pilot arc but dooesnt transfer to the main arc, the earth cable is in place, the consumables are all new.
Reading the trouble shooting section of the operators manual i have done the pilot arc test, d5 on the main control board is lit, d8 is not, i have 12 between pis 3 and 4 on cs1 and 12 v on pins 13 and 14 on the main board plug, the manual says this means i need to change cs1, part no 029202. Will this solve my problem? I googled the number and found nothing, is it igoing to be really difficult to get since im in the uk? could it be matched from a components supplier? When inspecting the consumables it appears the electrode has been arcing to the inside of the nozzle? is that normal and just caused by the fact the arc isnt transferring or does it mean something?? i can see lightening go from the torch to the plate and ive tried lots of different height settings.
Also when i fire the hf start the power of it is incredible, we have a good 3 phase supply and it makes all the lights in the shop flicker and also the lights in the house 5o yds away, it also makes my steppers move without even having my power supply or computer turned on, how can i stop that happening? im currently upgrading to servos, willl they deal better witht he hf or not?? Is the hf usually this powerful or is there something wrong there or its just being caused by running for too long because the arc doesnt transfer?
Thanks for any help
Matt
