As for why plasma don't raise, flame don't capacitance arc by high pressure?
至于为什么等离子不用电容调高，火焰不用弧压调高？
2
The high pressure and arc will rely on the arc, flame cutting is not appear the arc.
而弧压调高要依赖电弧，火焰切割是不出现电弧的。

Flame-retarding rigid polyurethane foam arc plate armoured with steel is a new type thermal insulation material developed by the Commercial Department of Heilongjiang Province.
