How To Off Set Welded Arms to Normal Position?

I am trying to weld the arms of the player to the head, so that they move with the head which moves with the camera angle.

This happens and I don't know how to return them to a position that I want:

Current Code

    Character:WaitForChild("Torso"):WaitForChild("Left Shoulder").Part1 = nil
    Character:WaitForChild("Torso"):WaitForChild("Right Shoulder").Part1 = nil


    local Lw = Instance.new("ManualWeld") 
    Lw.Parent = Character:WaitForChild("Left Arm")
    Lw.Part0 = Character:WaitForChild("Head")
    Lw.Part1 = Character:WaitForChild("Left Arm")

    local Rw = Instance.new("ManualWeld") 
    Rw.Parent = Character:WaitForChild("Right Arm")
    Rw.Part0 =  Character:WaitForChild("Head")
    Rw.Part1 = Character:WaitForChild("Right Arm")
