This research studied the rate of fast torch gas welding, mechanical arm cover Kawasaki model RA10N which affect the grade of steel SS400, size, thickness 3 mm, made of steel plate welding seam width 2 pieces 2.5 cm long, 10 cm in order to find out the rate of fast torch suitable for welding. Given the changes in the rate of fast torch 15, 20 and 25 cm per minute are contributing factors is the potential difference that 15, 20 and 25 volts electrical currents starting at 80 amperes 10 amperes increments until the work piece will be the result indicators (penetrated) by comparing the characteristics of the physical test weld with mechanical property toughness testing by impact.
