system variable for welder control

  • Hi,



    We have Fanuc arc mate 120ic/10L with R30iA controller and Kemppi 450 Arc.communication protocol ethernet 1p.
    We are doing a project in which robot is sensing the area of V groove and he has to change the welding parameter accordingly.
    We are not using conventional fanuc software of adaptive as it is not working on our kind of project.


    I have tried with a karel program and able to change the value of $AWESCH[1,1].$CMD_VOLTS and $AWESCH[1,1].$CMD_WFS,but when we are doing actual welding then parameters are not changing on the machine and result is poor weld quality.


    can any one guid me that which are the system variable in Fanuc which are responsible of transfering the voltage and wire feed value to welder.

  • I'm don't know about your version of Arctool, but at the 6.4 (ish) versions the description of the variables was wrong. For instance,
    $AWESCH[1,1].$CMD_VOLTS would actually control WFS;
    $AWESCH[1,1].$CMD_WFS would actually control Trim


    At least this was the case for Burn-back ($AWESCH[1,34]) and Wire stick ($AWESCH[1,35])


    I recommend setting up a test program, run it and verify volts write to volts and WFS to WFS etc. under your wels schedule!

  • HI,
    In my version of arctool it is giving correct values.
    The problem is that I am not able to tell my welder controller the voltage value as the system variables are write protected and I have to change the value of the variable in real time.


    If we go with conventional software then it is working it means all the hardware is correct.
    The problem we do not go with conventional method is that it is for Linear welding not for Circular welding and we have to do the circular welding

    Can confirm this on 7.7. Thought I was going crazy for a second. I was like "Uhhh, 500 volts at 150A....?"
