3 Types of Flames

• Neutral- equal oxygen
• acetylene
• Excess Acetylene- results in
• a feather look
• Oxidizing- Short with a
• roaring sound

While Working

• Watch the Regulators on the tanks
• Normal
• Open working pressure slightly decreases
• NOT Normal
• Open working pressure creeps and slowly increases

• Thickness of material determines pressure
  settings and torch tip size
• Oxyacetylene welding and cutting
• Works well with Mild and Carbon Steel
• Does not work with materials that have high
  melting points
