Name: Microcomputer digital control CO2/MAG automatic welding machine Model: XD350.500S Input voltage: three phase 380V Output Current: 350A current range :50-350A Weight: 113Kg Function: CO2 MAG features: First, penetration control function, even length of wire out there is a change, but also to maintain the stability of the welding power source. Second, the use of microcomputer control, to achieve complete unified regulatory function, easy to operate. Third, superior arc performance. Fourth, save energy, save gas, fan stop function, energy-saving control lines. Five, SCR overcurrent protection features that make welding more reliable. Six, can be easily connected with the automatic machine. A set of standard components, welding power XD350S * 1 2, torch WT3510-SD * 1 3, wire feeder CMXL-2303 * 1 4, CO2 gas meter CF-2503 * 1 5, welding cable BKPT-3502 * 1 OTC gas shielded welding corresponding product has the following models: ①, OTC gas welding: XD250C ②, OTC gas welding: XD200 ③, OTC gas welding: XD350.500S ④, OTC gas welding: XD600G ⑤ , OTC gas welding: CPVE350.500 ⑥, OTC gas welding: DL350II ⑦, OTC gas welding: DM350.500 1 full digital control welder: refers to the welding process control, power output figures are achieved control of welding two constant penetration depth control: GMAW welding power characteristic is flat and uniform feeding system, and the present is falling characteristic curve arc characteristics. When the torch height changes, such as elevation, the resulting arc voltage increases, current decreases, shallow weld penetration, contrary torch down the penetration depth becomes deeper, this has led to destabilizing effects of penetration weld quality. OTC developed penetration control, increasing the welding arc voltage feedback function and the shift wire system. When the gun elevation arc voltage becomes high, the arc voltage feedback system detects the change, the control system sends commands wire speed to ensure the stability of the current changes very little penetration, and vice versa. Constant penetration depth control functions can be effectively guaranteed in complex situations welding quality.
