Embodiment
It is below in conjunction with the accompanying drawings and specific real in order to be more clearly understood that the above objects, features and advantages of the present invention
Apply mode and make further nonrestrictive detailed description to technical solution of the present invention.
See Fig. 1 schematic diagrams, electric welding machine includes charger module, rechargeable battery pack, the first current-limiting resistance, the second current limliting electricity
Resistance, voltage-stabilized power supply, the first radiator fan and the second radiator fan.
The charger module of the present embodiment is conventional charger module, and it inputs termination civil power or generator, inputs 220V
Alternating current, output termination rechargeable battery pack.The charger module of the present embodiment includes three chargers parallel with one another, each
Charger controls independently of each other, and power output is 250W, therefore this charger module has three kinds of output modes：First
Kind is that a charger connects rechargeable battery pack, then power output is 250 watts, output current 5A；It is two and fills for second
Electrical equipment is parallel with one another, then connects rechargeable battery pack, then power output is 500 watts, output current 10A；The third is three
Individual charger is parallel with one another, then connects rechargeable battery pack, then power output is 750 watts, output current 15A.
The machine sets the purpose of three kinds of charging output mainly to consider that power output more hour uses, at charger module
In the first output mode, power output is 250 watts, and if not being welded incessantly to workpiece, this electric welding machine is still
Can be in normal working condition, and for electric power scarcity area ensure its good working order, as island,
Grassland, high and cold mountain area etc., when possessing abundant wind resource operation, the wind-driven generator carried can be used to provide charging.
In fact, in daily welding process, welder needs to clear up workpiece, repairing, changes welding rod, checks welding matter
Amount etc., so electric welding machine is typically in discontinuous work, the charger module of the present embodiment is substantially met needed for routine work.
