Change separation between row data from comma to tabulation

I have a code that copy past data from particular sheet to txt file however data row in txt separates by comma. What should I change in code in order that separation will be by tabulation ( key "Tab" in a keyboard )
Many thx in advance !

Option Explicit
Sub test()

    With Sheet1
        Set rRng = .Range(.Cells(8, 2), .Cells(.Rows.Count, 7).End(xlUp))
    End With
    Set TempSht = Sheets.Add
    rRng.Copy TempSht.Range("A1")
