SAE8
Adverse conditions mild steel electrode. Excels on rusty, greasy, poor fitting joints in all positions.
- Can weld through 1/2 inch (12mm) of surface contamination without porosity.
- Can bridge gaps as wide as 3/8 inch (9mm).
- Electrode can be bent without flux chipping.
- Slag can be welded over without removal.

APPLICATIONS:
Ideally suited for difficult maintenance repairs. Easily welds steels that have been galvanized, painted, rusted, or otherwise contaminated in service. Misaligned parts or difficult to access areas are also easily remedied with this electrode.

WELDING TECHNIQUES:
Weld with a short-medium arc length at low amperage. When surface preparation is impractical, use a medium-long arc and favor high amperages. Multi-pass welds can be made without intermittent slag removal. Use any welding technique from stringer bead to wide weave.
