TYPE OF CURRENT

Direct Current Electrode Positive (DCEP) or Alternating Current (AC)

RECOMMENDED WELDING TECHNIQUES

GENERAL: Electrode positive, work negative (DCEP) or Alternating Current (AC)
ARC LENGTH: Very short arc
FLAT: Angle electrode 10°-15° from 90°
VERTICAL-UP: Use weaving techniques
VERTICAL-DOWN: Not recommended
OVERHEAD: Use slight weaving motion within the puddle

STORAGE

RECONDITIONING

 After opening, store in holding oven 220°F to 350°F (104°C to 177°C) until used.

If exposed to atmosphere for extended periods, reconditioned for one (1) hour at 600°F (315°C).
