Designed to provide improved deposition rates, bead appearance and operator appeal over other electrodes of the same class when welding in low-temperature environments where low-temperature impacts are important. Excellent moisture resistance, good out-of-position welding capabilities and X-ray quality weld deposit
- Low moisture absorption rate
- Reduces worry of moisture pick-up and hydrogen cracking
- Easy slag removal
- Eliminates going back to oven for "fresh" electrodes
- Low spatter in all positions
- Reduces clean-up time
- Good wetting action
- Results in excellent weld bead appearance
- Reliable starts and restarts
- Enhances bead contour
- Very stable arc
- Provides better welds due to no porosity
- Easy to control
- 1.90 lb/hr at 90 amp deposition rate, 62.7% at 90 amp efficiency
- Flat, horizontal, vertical up, overhead welding positions
- Physical state: cored wire, form: coated rod, color: gray
- Increased toughness (impact strength)
- 22 volt
