 ===== 4.6 Consumables =====
   * **Wire spool size**: 16 x 100 mm diameter (inner x outer) x 44 mm.
+  * **Wire type**: The most common designations are **E71T-11** and **E71T-GS**. The //-11// is a wire for all positions and multi-pass welding while the //-GS// is a //general standard// usually suited for a single pass welding.
   * **Contact tip**: the tip has an M6 thread x 25 mm lenght. The torch consumables (tip and nozzle) should be compatible with the //Binzel standard// MIG torches **MB15**, also labeled as **AK15** by other manufacturers.
   * **Nozle**: 12 mm inner diameter, 52 mm lenght.

+===== Welding samples: 1 mm thich pipe =====
 These are some welding tests on a steel pipe (12 mm outer diameter, 1.0 mm thick), carried out at different current and amperage values. The wire used is a Telwin flux-cored 0.8 mm.
