Is there a way to weld a tool to a starter character to prevent the tool from falling?

[Strange_NTeeTee (Bakitkabaganyan)]

Problem:
A custom arm that was made for the robot(my starter character), is now a tool so a local script can run that is in it, the problem is, tool grip editor won’t help because my starter character isn’t a dummy rig, and nothing is anchored, everything is welded.

Desired output:

Just weld the tool handle to the robot with scripts.

(use Welds or WeldConstraint if you want it rigid, Motor6Ds if you want to animate it.)
