Tween welds rotatation

Hello, im trying to tween a welds rotation 360 degress, ive looked at many post but for some reason none of them are working. I looked at post on how to tween the part though, not the weld, i just guessed.

    local OneTomoeEye = script.Parent.OneTomoeLGS:Clone()
	OneTomoeEye.Parent = plr.Character.Head
	OneTomoeEye.CFrame = plr.Character.Head.CFrame
	local Weld = Instance.new("Weld")
	Weld.Parent = plr.Character.Head
	Weld.Part0 = plr.Character.Head
	Weld.Part1 = OneTomoeEye
	if plr.Character:FindFirstChild("Male") then
		Weld.C0 = CFrame.new(0.15,0.07,-0.325)
	elseif plr.Character:FindFirstChild("Female") then
		Weld.C0 = CFrame.new(0.15,0.03,-0.3)
	end
	Weld.C1 = CFrame.Angles(0,math.rad(0),0)
	--/where the tweening begins
	local info = TweenInfo.new(5, Enum.EasingStyle.Linear, Enum.EasingDirection.Out,-1)
	local properties = {CFrame = Weld.C1 * CFrame.Angles(0,math.rad(180),0)}
	local tween = ts:Create(Weld,info,properties)
	tween:Play()
	wait(5)
	tween:Play()
