• Welding cast iron structures such as bed, motor shield, etc.

Characteristics – applications: 

  • 33-VD is the electrode having a coating under the graphite group. Arc is stable without splashing and explosion.
  • Suitable for welding cast iron structures such as bed, foot, cabinet, motor shield, etc.
  • After welding high-hardness joints, able to process and cut.

Required Not required ≤ 0.03 ≤ 0.03
Obtained 2.8 ~ 3.2 0.5 ~ 0.7 3.0 ~ 3.5 0.025 0.024

Instructions for use:

  • Heat the object to be welded at 400 ~ 450 oC before welding
  • Drill holes at two heads of a break before welding
  • Clean oil, grease and dust before welding
  • Dry the electrode at 150 C for 30 ~60 minutes before welding
  • Process welding edges sufficiently so that the electrode can approach the welding area, avoid too large processing and thereby increase the risk for cracks due to shrinkage
  • Select appropriate welding current to avoid possible defects
  • Use AC or DC (+) power
  • Size of the electrode and used current:
