AC Or DC This electrode performs beautifully either way, Lincoln 7018AC is a great choice for low open circuit voltage AC power sources. Cold restrikes are no problem with this versatile, all-position electrode
- Medium penetration
- Low open circuit voltage operation
- Minimal spatter
- Capable of cold re-strikes
- Flat or slightly convex beads have distinct ripples with little spatter
- Single pass fillet welds on mild steel plate
- Flat, horizontal, vertical up, overhead welding positions
- 2 - 4mL/100 g weld metal diffusible hydrogen
