I am trying to move the C1 position in a weld but my script has an error why is this?

I am trying to move C1 in a weld but it isnt working :/

local Weld = Instance.new("Weld", Hand)
	Weld.Part0 = Hand
	Weld.Part1 = Fake
	Weld.C1.Position += CFrame.new(2,0,0)

Fake is a part. Hand is a player hand.

ERROR: Workspace.Sword.Script:58: invalid argument #1 (CFrame expected, got Vector3)

try using

Weld.C1.Position += Vector3.new(2,0,0)
