BUILD UP & HARDSURFACING
Wear personal protection equipment (PPE) at all times.
This includes eye protection, hard had, steel toe shoes,
leather gloves and hearing protection that conforms to
standards ANSI Z87.1 (Eye and Face Protection), ANSI
Z89.1 (Head Protection), ANSI Z41.1 (Foot Protection)

build up and hardsurfacing products. Using improper
products may result in premature wear or cracking of
the base metal.

Guidelines
• Connect the ground pole of the welder to the part to be welded, as close as possible to the welding area. The
ground pole must be connected so that the current does not cross the hinges or the hydraulic cylinder. If the
attachment is mounted on the operation machine during welding, follow the instructions int he base machine
manual to avoid damaging it’s battery or electronics.
• Carefully clean the area where material is to be added.
• Preheat to 302°F - 392°F (150°C - 200°C) and check the temperature frequently.
• Do not place more than two layers.
• Apply material with the grain of the parent material.
• Grind the ends of the fill material beads.
• After welding, cover the area with a heat blanket and allow to cool slowly.
• Carefully follow the application standards recommended by the man manufacturer of the fill wire.
