Help with indexing instances?

Why is this the loop on line 18 failing to make the "Right Arm" weld and why is it not being put in the table(the output prints table: 1EB7C178 )?How could I fix this problem and why is it doing this?

Player = game.Players.LocalPlayer
Character = Player.Character
Torso = Character.Torso
Mouse = Player:GetMouse()
----------------------------------------
function CharacterCheck()
    if not Character or Character.Parent == nil then
    Character = Player.CharacterAdded:wait()
    end
end
CharacterCheck()
----------------------------------------
function MakeWelds()
    local Arms = {Character["Left Arm"],
                  Character["Right Arm"]
    }
    local ArmWelds = {}
    for i,v in pairs (Arms) do
        local Weld = Instance.new("Weld",Torso)
        Weld.Name = v.Name.."Weld"
        Weld.Part0 = v
        Weld.Part1 = Torso
        ArmWelds[i] = Weld
        return ArmWelds
    end
end
Welds = MakeWelds()
print(Welds)
----------------------------------------
    LeftClick = Mouse.Button1Down:connect(function()
        print("LeftClick")
    ---Wip
    end)
