【SteelTailor Training Course】 Lesson One: Classification of Plasma

 

               Subject: Industrial Knowledge

                      Lesson I: Classification of Plasma

 Lecturer: Mr. Huang

__________________________________________________

From difference of current and gas, plasma can be classified as

Ordinary plasma, High definition plasma, Super Definition plasma.

Ordinary plasma basically takes bridge-current or IGBT current;

It is without shileding gas and cutting with air.

High definition plasma is applying IGBT current, like Hypertherm HPR series,

Victor VC series and Kjellberg HF80/165; While Kjellberg FineFocus and HF135

is applying thyristor; Kjellberg HF440 combines IGBT and thyristor. Besides,

high definition plasma enjoys shielding gas, cutting with air, oxygen, nitrogen,

argon and mixed gas.

 

Super Definition is an optimizing for CNC and software and realizing cutting effectiveness

by controlling direction, THC, overburning lead-out and arc closed in advance.

Tips: Life of consumables are related to current and piercing times.

Less piercing times, longer consumable life.
