The welding machine is a newly protrusive seam welding machine improved on the basis of original FN-1B,2B type seam welding machine.lt is with clamped gas pressure and stepless regulating three-phase motor.The procedure is finished respectively,which reflects that when switch is closed once,the gas cylinder will work;switch is closed twice,the motor will rotate and current will send out;switch is closed thrice,whole action will be finished With the function of advanced & stable & reliable performance,simple & convenient operation,large-current,adjustable small-step(coarse adjustment)and with pulse,it can meet various customers' requirements and is widely applied in the weld for sheet frame of oil tank,vent-pipe,instrument and outside shell.
