▎Welding Instruction

  • Dry the electrodes at 70-100°C for 30-60 minutes before use.
  • Clean up the contaminations on the steel to prevent porosity.
  • Preheat temperature should be above 150°C for multi-layer welding of low alloy steel or high carbon steel.
  • Welding parameter and operating technique must be carefully chosen to prevent slag inclusion in narrow gaps welding.

▎Applications

It is suitable for repairing sprockets, crane wheels, shafts and gear
wheels.
