摘要： An electrical welding device which requires no high frequency insulation and an electrical discharge gap for maintaining the arc discharge is made large. A main power source supplies an arc discharge current through an electrical conductor to the welding electrode. A high frequency electric power source applies a high-frequency high voltage between the electrode and the material to be welded to generate a high frequency discharge for arc ignition in the electric discharge gap. A high frequency magnetic choke element, which is preferably a plurality of stacked annular ferrite discs, surrounds a predetermined part of the electrical conductor. A high-frequency bypass capacitor is utilized to ground the electrical conductor between the magnetic choke element and the main power source.

摘要： Typically, a bottom of a cup-shaped electrode opposes to that of a similar electrode through a predetermined gap and in a mixture of helium and hydrogen. A step-up transformer connected across an AC source through a resistor applies a voltage in excess of a discharge breakdown voltage for the gap across the electrodes to cause a pilot glow discharge between them before the source voltage reaches a glow hold minimum voltage for the electrodes. A rectified voltage resulting from a transformer connected across the resistor turns a bidirectional triode thyristor on to apply the source voltage across the electrodes through the conducting thyristor. This smoothly transits the pilot glow discharge to a glow discharge between the electrodes. The latter discharge heats a liquid forcedly flowing along inner surfaces of the electrodes. Also an auxiliary electrode can be operatively coupled to the electrodes to cause similarly a pilot glow discharge between it and either one of the electrodes. For a DC source a tubular anode surrounds a middle portion of a tubular cathode through which a liquid flows.
摘要翻译：通常，杯形电极的底部通过预定间隙和氦和氢的混合物与类似电极的底部相反。通过电阻器连接在交流电源上的升压变压器对电极之间的间隙施加超过放电击穿电压的电压，以在源电压达到电极的辉光保持最小电压之前在它们之间引起导频辉光放电。由连接在电阻器上的变压器产生的整流电压使双向三极管晶闸管导通，通过导电晶闸管将源极电压施加到电极两端。这样平滑地将导频辉光放电转移到电极之间的辉光放电。后者的放电加热了沿电极的内表面强制流动的液体。还可以将辅助电极可操作地耦合到电极，以类似地引起其与电极中的任一个之间的导频辉光放电。对于DC源，管状阳极围绕液体流过的管状阴极的中间部分。
