Tri-mark triple 7 flux cored carbon steel welding wire
2 PARTIAL SPOOLS OF TRI-MARK S285812-K29 .O45"
is designed for the semi-automatic gas-shielded welding of carbon steel and some higher strength
steels where requirements and conditions do not exceed its capabilities. It is intended for single and multiplepass
welding in all positions and has a fast-freezing slag that permits the welder to use higher current to deposit
more metal faster and still produce a flat bead in all positions. The slag removes easily even from deep groove
weldments and spatter is low, so a welder spends more time welding and less time cleaning up. The X-ray quality
surpasses the radiographic specifications of AWS A5.20 and ASME SFA 5.20 when welded with the recommended
heavy gauge sheet metal, pressure vessels, and certain pipe weldments.
Excellent weldability with 100% CO

diameter electrodes was welded using 100% CO2 shielding gas with flow rate of 40 cfh, 275 amps (240
ipm), DCEP, and 27 volts, and using 75% Ar/25% CO
2 shielding gas with flow rate of 40 cfh, 275 amps (240 ipm),
DCEP, and 26 volts, both with 3/4 electrical stickout and 300 25 F Interpass temperature. A total of six layers
two passes each for Layers 1 through 6. The direction of travel was reversed for each layer.
