Smooth cut face
•
Virtually no dross
•
Shield gas is normally nitrogen. A small amount of oxygen combined
with nitrogen can effectively improve dross formation on thin material of
26 GA to 10 GA carbon steel. Also, an oxygen only shield may provide
acceptable results on thinner materials.
Smooth cut face
•
Virtually no dross
•
Cutting carbon steel with oxygen results in an exothermic reaction. This
chemical reaction causes the carbon in the material to burn similar to
when oxy-fuel cutting. This plus the electrical energy uses lower
amperage levels without sacrificing cut speed.
