Setting Up The Welding Machine

• Steel: Use DC straight polarity and an electrode with a red end (2% Thoriated). When welding steel with DC straight polarity make sure the tip is ground to a conical point.
  
  
• Aluminum: Use AC current and an electrode with a green end (100% Tungsten) Ensure that the tip is round properly.
  
  
• Other Material: Consult welding reference or experienced welder.
  
  
• Amperage varies depending on material thickness and type of weld.
