Riba - can i use 1N4004 diode instead of 1N4001? Only difference is voltage if im not wrong.
Looks like the old PIC K150 Programmer will also work.riba2233 said:It's simple once you have a programmer like pickit 2 or 3 with their own software, just connect it to pc, load the hex file, and press programkrlenjuska said:Most difficult thing to do for me is to program pic controller - never tried this![]()

Thank you

wakko said:Riba - Apologies, I've found that the function Get_ADC_Sample is included in the mikroC PRO libraries. I'm new to using mikroC PRO so I didn't know they had these libraries. I find that when you open the .mcppi file in mikro C PRO it refers to a source document called sw_pot.c but reports it as missing. I'm guessing the mcppi file is just a project file whilst the actual source code is saved separately as .c files. However you can simply rename Code.txt to sw_pot.c and it'll load up correctly.
Yes. If you have a pacemaker, don't let the welding cables get close to your chest. I think you'd have to be pretty close to actually cause a problem. More than a foot away should be OK.tomjasz said:Kweld mentions their welder can create issues with a pacemaker.
"This system produces significant magnet fields, do not use it when you have a cardiac pacemaker!"
Is this a concern with the JPWelder?
