Handheld Fiber Laser Welding Machine SMW-1000/1500/2000
Used to provide the energy required for welding. Commonly used are various arc welding power sources, also known as welding machines. Its no-load voltage is 60-100 volts, operating voltage is 25-45 volts, and output current is 50-1000 amperes. During manual arc welding, the arc length often changes, causing changes in welding voltage. To ensure stable welding current, the external characteristics of the arc welding power source used should be steep, that is, with the change of output voltage, the change of output current should be very small. Gas shielded arc welding and submerged arc welding can use flat characteristic power sources, and their output voltage changes very little when the current changes. Arc welding power sources generally include arc welding transformers, DC arc welding generators, and arc welding rectifiers. Arc welding transformers provide AC power and are widely used.
