Notice:
1.The electrode with titanium-calcium coating must be stoved at 200-300℃ for 1 hours prior to use.
2.The welding consumables surface rust, oil fouling and other impurities must be cleaned up.
3.The welding slag must be cleaned up in the multi-pass welding. The inter-pass temperature should be controlled below 150 ℃.
