The joint while tining that is used for many group copper conductors.The scolding tin energising heating of about 4/5 volume will be of the present utility model put in the pot body, after scolding tin melts fully, firm scolding tin can be hung treating to be stained with after the coated with flux on the joint area of tining in the tin water of pot body.
2, water the tin method
For 16mm
2Above copper wire lead or the main line branch between the floor, the normal tin method of watering that adopts, the scolding tin energising heating of capacity will be put in the pot body of the present utility model, horizontal and the coated with flux of joint area furnishing of tining will be treated, lie in the top of the energising Electric tin pan of the bigger pot body internal diameter that a small amount of scolding tin is housed, water Xi Shui from above with the utility model of containing tin, Xi Shui waters after the sky in the pot body, pours into from big mouthful of following Electric tin pan and supplies.When just watering, because the temperature of joint does not raise, scolding tin has the phenomenon of condensing, and should continue to water tin, make joint improve temperature, and the tin that waters capable of circulation is till joint all welds.
The utlity model has the temperature constant function, make scolding tin keep meltability, but when adopting above two kinds of methods to do continuous tining work, liquid scolding tin temperature is reduced and cause easily solidifying, this moment should be then very convenient to continuing the heating of heating shelves with switch transition.
When the utility model need be placed on the body surface of floor etc. being afraid of to scald, the support that can amount to can be opened and form two front fulcrums, downward projection then forms a rear fulcrum on the handle club handle, and three fulcrums can hang pot body of the present utility model, handle bar to put, with the surface isolation on floor.Projection on the handle club handle had both helped gripping stable, and it is convenient to help taking and placing again.
Good effect of the present utility model is:
To use molten tin of portable Electric tin pan and the molten tin of blowtorch to contrast its result such as following table:
| Portable Electric tin pan melts tin | Blowtorch melts tin | |
| Reach dependence heat time heating time to the people | There was not nurse in 1～15 minute | Strict nurse in 15～20 minutes |
| Mode of heating | The heating of 220V alternating current | The naked light heating |
| Security | Safety | Dangerous |
| Energy consumes | Electric energy 0.15～0.3KWH | 0.2 liter in gasoline |
| Pollute | Do not have | Have |
| Efficient | Can add thermal weld continuously to many set of joints | Heating once can be welded a set of joints |
1, the utility model only need can be realized flames of anger constant temperature with the AC power of job site or continue heating, can make Xi Shui remain at the temperature that to work, whether power supply connects is seen that indicator lamp comes into plain view, and can improve the construction quality of copper wire lead soldering in the electrical installation project or tining.
2, the handle bar is fixedlyed connected with being connected to of body of pot, not only has the tin sticky function, but also can water tin, uses flexible operation, and is easy to carry, increases work efficiency.
3, safety and environmental protection., select the heated at constant temperature shelves or continue heating shelves power supply heating, by using switch flexibly in difference construction occasion to save electric energy; The support that can amount to is arranged, can place during intermittence in the body surface operation of being afraid of to scald; Need not fuel naked light burning heating, can initiation fire.
