Weldwell PH77 Electrode
The Weldwell PH77 is a low-hydrogen electrode containing iron-powder in the coating. PH77 is designed to weld in all positions except vertical down. The welding arc of PH77 is very quiet and with very little spatter and the weld metal deposits exceptionally smoothly with excellent wash to the weld sides which practically eliminates undercutting. The slag is easy to control and is easy to remove after welding. Compared to the general types of low-hydrogen electrodes the PH77 performs nearly like a rutile electrode with low-hydrogen results.
- Available in 2.5, 3.2 & 4.0mm
- A low hydrogen controlled electrode
- Suitable for all positions (except vertical down)
- Exceptionally smooth welding
- For low alloy, high tensile steels and steels to LT40 specification
