The Forney 30305 6013 Mild Steel superweld Welding Rod is a mild steel, all-position general purpose rod with medium to shallow penetration. Medium to heavy slag is easily removed. Excellent for poorly fitted joints. Smaller sizes of rod are well suited to low heat on thin metals. 3/32-Inch ie.2.38 mm rod diameter. 5-Pound ie.2.26 kg. 6013 Tensile strength is 60,000 PSI Amperage 40-80 amps AC, DCEN, DCEP Either Polarity. Typical Spec Example E6011: E is for electrode. The next two numbers ie.60, 70 or 80 indicates the tensile strength of the rod for example 60,000. The third number tells the welding position; ie.1=All position ie.2=Flat or Horizontal position ie.4=Flat, Horizontal, Overhead and Vertical Down position. The fourth number indicates the type of current to be used and coating of the rod; ie.0=Cellulose Sodium, with deep penetration, use Direct Current Electrode Positive ie.1=Cellulose Potassium, with deep penetration, use AC or Direct Current Electrode Positive, or Direct Current Electrode Negative ie.3=Titania Potassium, with light penetration, use AC or Direct Current Electrode Positive ie.8=Low Hydrogen, Iron Powder, with medium penetration use AC or Direct Current Electrode Positive.
