Buildup and joining of manganese steels and carbon steels
Hardness: Up to Rc 54 (3rd pass)
No. of Passes: Up to three
Polarity: DC Reverse
Gas: None or 75% Ar, 25% CO2
Typical Applications
• Bucket teeth
• Hammer mill and mill swing hammers
• Tampers and jackhammers
• Impactor crusher bars
Usage Procedure
When CRONALLOY EAGLE 7109M-FC is applied via the open arc method, high deposition rates are possible. Weld current of 28-30V/250A will give a deposition of approximately 12lbs./hr.
DC current, reverse polarity is preferred for better arc stability. For general hardfacing, wire stickout may vary from 3/4" to 1-1/2". On low current applications (175 – 240 amps), approximately 1" stickout should be maintained.
The hardness figures shown are typical, and variations, higher or lowe
