Use of IC electronic control, synchronous circuit, and the electric current is 
    controlled by S.C.R. solidstate switch stageless adjustment.

Upper arm electrode brass can be adjusted 360º to weld accuratly in 
    horizontal and vertical requirement. Lower arm chrome electrode brass can
    be changed for application of both horizontal and vertical welring.

Power transmission is used of variable speed change so as to be adjusted for
   needed accurate speed, and the upper and lower chrome electrode brass is
   desingned for synchronous running in welding.
