Welding Tips and Tricks

hi mate, can you give me some tips what is this connection for?

Remote pedal or torch switch.

It says external view. With the pins labeled by letters. Off to the left is the letter diagram that tells you what each pin is for. And then down below those are the pin labels for if your using it on a robotic welder.

thanks mate,hope that everything comes easy when using this machine...i check this in you tube how to assemble this but no english demo,all in france version.
