Smoothcor 81T1-Ni1 is a low alloy steel electrode for flux cored arc welding with external gas shielding. This electrode is intended for single and multiple pass welding, in all positions, on carbon and low alloy steels requiring good charpy v-notch toughness at subzero temperatures. Both 100 percent carbon dioxide and 75-80 percent argon balance carbon dioxide can be utilized with smoothcor 81T1-Ni1. A recommended gas flow rate of 35-50 cfh should be maintained, along with a minimum dew point of -40 deg F
- Rutile based slag system, which exhibits a spray-like arc transfer and very little spatter
- Proprietary core ingredients provide a fast freezing slag which facilitates welding in all positions
- Slag volume is moderate and removal is quite easy
- The use of 75 - 80% argon balance carbon dioxide enhances the fast freeze nature of the slag, thus allowing slightly higher currents in all position welding
- Modern manufacturing technology ensures the highest level of quality and a very uniform distribution of core ingredients throughout this product
- For welding steels requiring good tensile strength in excess Of 80000 psi and charpy v-notch toughness (20 ft-lb) as low as -40 deg F
- 25 volt (vertical up), 26 volt (overhead), 28 volt (flat)
- 265 in./min. (overhead/vertical up), 282 ipm (flat) wire feed speed
