EXTRAORDINARY MAINTENANCE
To add material use 57 HRC (600 Brinell) fill wire, Ø 1.2 mm K 300.
The recommended wires are:
UTP: A67S Ø 1.2 mm
FORTARGEN: A7111 MIG Ø 1.2 mm
DANGER!
Before adding material, it is necessary to turn off the operating machine and wear suitable IPDs (gloves,
goggles, safety shoes and suitable clothing).
