Review Questions

• How does the use of alternating current enhance the performance of a plasma torch compared to direct current?
  • Using alternating current in a plasma torch allows for better stability and control of the plasma arc. Unlike direct current, which maintains a constant polarity, alternating current switches between positive and negative cycles. This results in more efficient ionization of the gas, creating a hotter and more stable plasma stream that can be precisely adjusted for various applications like cutting or medical treatments.
• What specific applications benefit from the unique characteristics of alternating current plasma torches in the field of Plasma Medicine?
  • In Plasma Medicine, alternating current plasma torches are particularly useful for procedures such as tissue ablation and sterilization. Their ability to produce high-temperature plasmas allows for precise removal or modification of biological tissues without causing excessive damage to surrounding areas. The controlled energy delivery and reduced thermal load make these torches ideal for sensitive medical procedures where precision is crucial.
• Evaluate how safety measures related to alternating current plasma torches impact their use in both industrial and medical settings.
  • Safety measures for alternating current plasma torches are essential due to the high temperatures and hazardous radiation they generate. In industrial settings, proper shielding and protective equipment are necessary to prevent burns and injuries from ultraviolet light exposure. Similarly, in medical applications, protocols must be in place to protect both patients and healthcare providers from potential hazards associated with high-energy operations. Effective training and adherence to safety guidelines ensure that these powerful tools can be used effectively without compromising safety.
