I have a running animation which moves the arms, however, when you hold a gun, it does not go along with the arms.
I noticed I had to weld it. I tried to weld a brick to my right arm and it worked, but when I weld any type of tool to my hand it doesn't work.
How do I do this?

This is sounding a bit more like a building question
weld all parts in the tool to a handle, and weld the handle to your arm.
