Build Up Instructions
Wear personal protection equipment (PPE) at all times
maintain LaBounty products.
1. Disconnect InSite power cable before welding.
2. Throughly clean the area to be built up.
3. Preheat the area to 200° F (94° C) to remove moisture.
4. Heat the area to be built up to 400° - 450° F (204° - 233° C).
Note: Do not exceed 450° F (233° C)
5. Using AWS E7018 welding rod, make side by side
underlayment beads.
6. Relieve stress and remove slag after each pass by peening
vigorously with an air operated slag peener.
Note: Check the temperature often. Maintain 400° - 450° F
(204° - 233° C).
