I have been messing with the "fromEulerAnglesXYZ" for a hour trying to change the rotation of the weapon when the player is holding it and I can't change the rotation at all. could anyone please explain how I would?

Tool = script.Parent;
local humanoid = nil
local arms = nil
local torso = nil
local welds = {}

function Equip(mouse)
	wait(0.01)
	humanoid = Tool.Parent:WaitForChild("Humanoid")
	if humanoid.RigType == Enum.HumanoidRigType.R15 then
		arms = {Tool.Parent:FindFirstChild("LeftUpperArm"), Tool.Parent:FindFirstChild("RightUpperArm"),Tool.Parent:FindFirstChild("LeftLowerArm")}
		torso = Tool.Parent:FindFirstChild("UpperTorso")
		if arms ~= nil and torso ~= nil then
			local sh = {arms[1]:FindFirstChild("LeftShoulder"), arms[2]:FindFirstChild("RightShoulder"),arms[3]:FindFirstChild("LeftElbow")}
			if sh ~= nil then
				local yes = true
				if yes then
					yes = false
					sh[1].Part1 = nil
					sh[2].Part1 = nil
					sh[3].Part1 = nil
					local weld1 = Instance.new("Weld")
					weld1.Part0 = torso
					weld1.Parent = torso
					weld1.Part1 = arms[1]
					weld1.C1 = CFrame.new(1, 0.2, 0.1) * CFrame.fromEulerAnglesXYZ(math.rad(-90), math.rad(50), 0)
					welds[1] = weld1
					local weld2 = Instance.new("Weld")
					weld2.Part0 = torso
					weld2.Parent = torso
					weld2.Part1 = arms[2]
					weld2.C1 = CFrame.new(-1.2, -0.2, 0.15) * CFrame.fromEulerAnglesXYZ(math.rad(-75), math.rad(-10), 0)
					welds[2] = weld2
					local weld3 = Instance.new("Weld")
					weld3.Part0 = torso
					weld3.Parent = torso
					weld3.Part1 = arms[3]
					weld3.C1 = CFrame.new(1, 0.8, 0.1) * CFrame.fromEulerAnglesXYZ(math.rad(-90), math.rad(50), 0)
					welds[3] = weld3
				end
			end
		end
	else
		arms = {Tool.Parent:FindFirstChild("Left Arm"), Tool.Parent:FindFirstChild("Right Arm")}

					welds[2] = weld2
				end
			end

	end
