MG 506W 

Flux 

-cored wire for maintenance and repair 

welding of carbon and mild steels 

GENERAL CHARACTERISTICS: 

The special formulation of this gas-shielded, flux-cored wire allows it to be used in many of the same 

applications as MG 506 coated electrode. Use for single or multipass flat and horizontal welds on carbon and 

some low alloy steels where dirt, grease and paint cannot be removed prior to welding. Almost slag-free welds 

reduce cleanup time and increase deposition rates resulting in overall lower welding time. Designed for the 

maintenance and repair welder. 

APPLICATIONS: 

Use to fabricate and repair carbon and low alloy steel, plates, structural components and machinery parts. 

Excellent for short intermittent welds. Use where proper cleaning of the weld area is impractical or impossible. 

Designed to make the quick repair where proper cleaning of the weld area is not possible. 

 TECHNICAL DATA: 

Typical Tensile Strength Up to 80,000 psi (552 N/mm2

) 

Typical Yield Strength Up to 86,000 psi (469 N/mm2

) 

Elongation Approx. 26% 

Polarity DCEP (electrode +) 

Shielding Gas 75% Argon, 25% Oxygen, flow rate 35-50 CFH 

.045” Spray Arc Flat and Horizontal 

Amperage Volts Wire Feed Speed (in/mm) ES (Electrical Stickout) 

200 27 280 1/2” - 3/4" 

300 32 515 1/2” - 3/4" 

PROCEDURE: 

Clean the weld areas as much as possible. Set the wire feeder as shown above. Set gas flow as shown. 

Stickout should be 1/2”. Drag or push technique can be used. (Drag: Wire is pointed in the direction toward the 

completed weld. Push: Wire is pointed in the direction the weld is being made.) Multi-pass welds can be made 

without slag removal.
