Can anyone help and explain how to easily shift our entire program, it a Fanuc welding robot RJ3 controller, we have parts jigged up and programmed a new torch has been fitted and the torch is slightly different is there a way to shift the whole program to suit the new torch? As you can guess we are new to this and it was a mammoth task for us to write our programs

I think the best way is to change your toolframe, that would solve all problems.

When you did not have used a toolframe, you can make a toolframe that contains the difference between the old tool and the new one.

You may have to touch up all your weld starts and stops in this program.  This may sound like A large task for someone new to this, but this is done very easily.  You can try to shift your whole program, but surely you will have to touch up some points anyway.
 You did not say what type of welding you are doing, but i assumed it was MIG.  Most times the easy way is not the best way to fix A problem.  You may have to touch up all your programs.  Have seen posts about making tooling for locating the new torch as close as possible when changing. May not be A bad idea for future changes.

When you have to do A bunch of touch ups, I like to put robot in jog frame.
This will allow you to just use X,Y,and Z buttons unless you have A rotating table that holds the fixture.
You said this was from torch replacement, so the table most likely will  not need to be  moved.
Good luck, this is good practice, you will get very fast at this. Just don't forget to hit touch up after every adjustment.

I agree with Kluk-kluk.  Toolframe values will take care of your problem.
