STEEL – STEEL WELDING
CAUTION
Before welding, perform multiplex modules disconnection procedure.
NOTE
Welding surfaces must be free of scale, slag, rust, paint, grease, humidity or other foreign material that
would render welding impossible.
DANGER
Only a qualified and experienced person must do welding.
o
FCAW (Flux Cored Arc Welding) process ;
o
Electrode wire conforms to A5.20 AWS (American Welding Society) specifications ;
o
E4801T-9-CH, type electrode wire with 0,045“ diameter (1,14 mm) ;
Material Thickness Voltage Current Wire Feed Rate Shielding Gas
1/8” to ½” 26 ± 2 volts 260 Amps 450 ipm. approx.
75% argon – 25%
CO2 or 100% CO2
If necessary and with great care to prevent perforating the material, it is possible to use a conventional
electric arc welding machine according to the following specifications:
o
SMAW (Shielded Metal-Arc Welding) process ;
o
Welding rod conforms to A5.1 of AWS (American Welding Society) specifications; E 7018 type
welding rod with 1/8” diameter (3,2 mm).
o
Current: 100 amperes to 150 amperes; optimum at 120 amps.
It is important to grind weld bead starts and stops and also to grind arc strikes from surfaces.
