Features
- Reliable, general purpose electrode
- For manual metal arc welding of carbon steels, carbon manganese steels and fine-grained carbon manganese steels with elevated yield strength
- Deposits a tough, crack-resistant weld metal
- Low moisture absorption type coating
- High welding speed in the vertical-up position
- Insensitive to the composition of the base material within fairly wide limits
- Can be used for welding structures where difficult stress conditions cannot be avoided
- H4 R approved
- Low diffusible hydrogen to reduce the risk for cold cracking
- Outstanding low moisture pick up
- High efficiency bringing productivity
- Extremely good weldability in vertical up position
- Exceptional weld appearance
- Smooth, stable arc with very low spatter
- Excellent arc starting is enhanced by a special graphite tip on the electrode
- Complete slag coverage provides easy removal and minimal post weld clean-up, improving productivity
- Intended for a wide variety of carbon, low alloy, and hard enable steels
