  Impulse refers to the welding current waveform is discontinuous, current size changes.   Generally speaking, pulse type spot welder refers to the sinusoidal alternating current is SCR, divided into sections of current, commonly known as pulse welder. In other words, pulse mode of operation refers to the mode of operating only once every certain interval.   At present, single pulse and double pulse are mostly used in welding.   Conventional pulse gas welding: only one pulse. All the peaks of a monopulse are the same like NNNNN. Pulse gas welding machine is the use of pulse current to achieve droplet transition welding mode, no splash, deep penetration, fine grain, high weld strength, suitable for all-position welding, from 20 a to 500A can achieve stable quality welding, welding performance is far better than the ordinary gas welding machine, is the mainstream direction of welding machine development. Double pulses are equivalent to the superposition of two single p...
