Use drive rolls with a V-groove and flat pressure rolls. ✓ Use knurled rolls only when friction in the liner causes smooth rolls to slip . with long, extremely curved cable assemblies. Knurled rolls give increased liner and contact tip wear. ✓ Check that the groove size is correct for the wire diameter. ✓ Apply the correct pressure on feed rolls. Too much pressure flattens the wire, resulting in feedings problems and higher liner and contact tip wear. Insufficient pressure may cause wire to slip in the feed rolls, resulting in irregular feeding and possible wire burnback | ESAB Welder guide book ALL-POSITIONAL RUTILE FLUX CORED WIRES FOR NON AND LOW ALLOYED STEELS XA 00150520 Contents Introduction 3 Direction of travel 18 Before you start welding Contact tip and gas nozzle Polarity and inductance Welding parameter setting ASME and EN ISO positions Choice of wire size Recommended parameter settings 4 Welding positions 19 8 Vertical up 10 welding techniques 22 11 Split-weave and 13 stringer beads 23 14 Mechanised welding 24 Grinding 26 16 Trouble shooting 27 Product AWS OK Tubrod E71T-1C H4 E71T-1M H8 OK Tubrod E71T-9 H4 OK Tubrod E71T-1C E71T-1M FILARC PZ6113 E71T-1C H4 E71T-1M H8 FILARC PZ6114 E71T-1MJ H4 FILARC PZ6114S E71T-1CJ H4 Dual Shield 7100 Ultra E71T-9C H8 E71T-9M Dual Shield 7100 LH E71T-1C E71T-1M Dual Shield 7100S E71T-1C OK E71T-1 E71T-1C H4 E71T-1M H8 71T E71T-9C H8 AWS OK Tubrod E81T1-Ni1M FILARC PZ6116S E81T1-K2 J H4 FILARC PZ6138 E81T1-Ni1M JH4 FILARC PZ6138 SR E81T1-Ni1M J FILARC PZ6138S SR E81T1-NÍ1C J AWS Dual Shield 55 E91T1-Ni1M Dual Shield 62 E101T1-G Dual Shield II 81-K2 E81T1-K2 OK Tubrod E111T1-K3MJ-H4 2 Introduction This guide provides practical information on the use of the ESAB all-positional rutile cored wires listed below. When correctly applied these wires provide Excellent weldability with spray arc droplet transfer in all welding positions. Good weld appearance with smooth weld metal wetting. High productivity especially in vertical-up position. Defect free welds with good mechanical properties. Low-hydrogen weld metal.
