Description
Technical field
The utility model belongs to the electric welding machine technical field, is specifically related to a kind of portable contravariant stick arc welder.
Background technology
At present, portable contravariant stick arc welder application scenario is very wide, can be used for work high above the ground, field work, indoor and outdoor decoration etc., have carry easy, advantages such as processing ease, its weak point is: the one, high pressure in the existing portable contravariant stick arc welder and low-voltage circuit hybrid junction in the circuit board, if FET explodes or the situation of other high-low pressure short circuit appears in machine, easily electric leakage, if shell does not have ground connection, the serious consequence that can cause electricity to be hurted sb.'s feelings, the 2nd, the heater element on the electric welding machine on high-tension circuit and the low-voltage circuit is not isolated at radiator yet, and these all can cause potential safety hazard; The 3rd, portable contravariant stick arc welder does not on the market all have the electric current Presentation Function, and the user can not see welding current intuitively, is unfavorable for safety in production.
Summary of the invention
The purpose of this utility model provides a kind ofly to be had high pressure and low-voltage circuit and installs, on radiator high pressure and low pressure are isolated in the subregion in the circuit board, can intuitively show the portable contravariant stick arc welder of function such as welding current.
The utility model is achieved in that portable contravariant stick arc welder, mainly include: high and low pressure circuit, radiator and power switch, described high-tension circuit and low-voltage circuit divide two zones to install in the circuit board, described radiator has three at least, be connected with heater element in the low-voltage circuit with high pressure respectively, display floater is provided with the digital display that can show welding current.
Be separated with 5-20 millimeters safe distance between between high-tension circuit on the above-mentioned wiring board and the low-voltage circuit.
Three above-mentioned module radiators, top one connects high-tension circuit, and following two connect low-voltage circuit.
The utility model mutually compared with prior art, outstanding advantage is:
1, high-tension circuit and low-voltage circuit divide two zones to install in the circuit board, occur that FET explodes or break down in other high-and low-voltage circuit and the earth-free situation of shell under, the high-and low-voltage circuit is not easy short circuit, uses safer;
2, because high pressure, low voltage component are used different radiators respectively, guaranteed the isolation on radiator of high pressure, low pressure;
3, digital electronic ammeter can be told the size of user's welding current very intuitively;
4, the technology serviceability of complete machine of the present utility model is more perfect, is applicable on various types of arc welders and applies.

The specific embodiment
With specific embodiment the utility model is elaborated with reference to the accompanying drawings, shown in Fig. 1-5:
Portable contravariant stick arc welder, mainly include: height, low-voltage circuit, radiator and power switch, described high-tension circuit and low-voltage circuit divide 1 in the circuit board, install in 2 two zones, wherein zone 1 connects low-voltage circuit, zone 2 connects high-tension circuit, be separated with 12.6 millimeters safe distance between between high-tension circuit on the wiring board and the low-voltage circuit, high-tension circuit and low-voltage circuit are separated, described radiator has three at least, three module radiators 5 above the radiator connect the heater element in the high-tension circuit, below two module radiators 4 be connected with heater element in the low-voltage circuit with 6, high pressure heater element and low pressure heater element are isolated by radiator, it is digital electronic ammeter 7 that display floater 12 is provided with the digital display that can show welding current, makes the user can see the size of welding current intuitively.
The front panel of portable contravariant stick arc welder (referring to Fig. 3) structure includes: power supply indicator 10, unusual indicator lamp 9, power switch 11, output head anode 13, negative pole of output end 14, welding current regulator potentiometer 8 and digital electronic ammeter 7; Rear board (referring to Fig. 5) structure includes: blower hood 25, power input mouth 26; Internal structure (referring to Fig. 4) includes: cowling panel 17, input power panel 16, radiator 4,5,6, support bar (weak point) 15, support bar (length) 18, blower fan 19, support 22, master control borad 21, footing 20, output elbow 24, output reactance 23; Also has shell 3.
The use of the utility model welding machine: the positive pole that earlier the electrode holder line is connected front panel, workpiece connects negative pole, the other end of ground connection pincers is connected with black snap joint, the input port 26 of connecting with the mains again, power supply indicator 10 is bright, turn on the power switch 11, blower fan 19 begins rotation, according to the operation needs, regulate welding current potentiometer 8, make welding performance reach requirement after, the beginning welding job, at this moment, the size that can very show welding current on the Current Display 7 of this portable contravariant stick arc welder front panel 12 intuitively, and electric welding machine high pressure and low-voltage circuit have been realized subregion on 1,2 zone of wiring board, if occur that FET explodes or machine occurs breaking down in other high-and low-voltage circuit and shell 3 earth-free situations under, the high-and low-voltage circuit is not easy short circuit, is unlikely electricity and hurts sb.'s feelings, and three radiators also dispel the heat to the heater element in high pressure and the low-voltage circuit respectively, weld job finishes, and closes the welding machine electric power switch.And close the power switch of power distribution equipment, it is as safe as a house that this portable contravariant stick arc welder is used, and it is perfect that the supporting technology of equipment also more becomes.
