The utility model novel structure is simple, and volume is little, and is in light weight, safe in utilization, easy to carry, and the special occasions that can be widely used in no alternating current uses the problem of electric welding machine, is the innovation on the electric welding machine.
Description of drawings
Fig. 1 is a three-dimensional structure diagram of the present utility model.
Fig. 2 is a control circuit schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
Provide by Fig. 1,2, the utility model comprises lithium ion battery group, the control circuit in housing and the housing, housing is equipped with electrode holder 3 on 1 side, handle 2 is arranged at housing top, power switch 4, current adjusting knob 5, indicator lamp 6 are arranged on the housing front panel successively, the control circuit of electrode holder, power switch, current adjusting knob and indicator lamp and inside links, and the power end of control circuit is connected to the lithium ion battery group into the electric welding machine power supply, and the ground wire 7 that stretches out housing is housed on the ground end.
Described control circuit is; battery pack E(is the lithium ion battery group in the housing) be serially connected with resistance R 1 between both positive and negative polarity; R2; resistance R 1; the transition joint of R2 links to each other with the base stage of triode BG; the colelctor electrode of triode BG connects the positive pole of battery pack through relay J; form battery pack E holding circuit; the emitter stage of triode BG connects the negative pole of battery pack; resistance R 3; potentiometer W(is the current adjusting knob 5 among Fig. 1) and the field-effect driver IC; power switch K(is the power switch 4 among Fig. 1) connect the field-effect driver IC; and connect the source electrode of high-power FET BG2 and the positive pole of battery pack E through relay contact J1; the grid of high-power FET BG2 connects the field-effect driver IC; the drain electrode of high-power FET BG2 connects electrode holder 3; electrode holder meets current sensor Q; current sensor Q connects potentiometer W and resistance R 3 in parallel; indicator lamp D(is the indicator lamp 6 among Fig. 1) a termination power K switch and field-effect driver IC; the negative pole of another termination battery pack E, field-effect driver IC connect the intermediate regulations contact of the potentiometer W that regulates welding current.
