1 |
Eyes can't adapt to the flame. |
After adding Flux,the flame is stronger than before |
Wear the sunglasses,through an adaptation period of about one week |
2 |
The melting speed of the solder is relatively low. |
①Pressures are not enouth,weld temperature is relatively low.
②Heating time is too short,weld temperature is not enough. |
①Adjust the pressure of gas
②Lengthen the heating time,put the solder wire after the coper pipe is heated to corresponding temperature |
| 3 |
The leakage increases |
①There is more impurity in solder.
②Improper operation |
①Adjust the solder properly
②When the coper pipe is heated to corre sponding temperature,you should put the solder wire to the position opposite to the firing pointon the coper,and make it melt naturally,flow to the firing point on the coper automatically.As to the two-end weldingtorch.you should pay attention to the action of shutting the welding torch |
| 4 |
The pipeline is blocked |
The fluxing agent volatilizes andleads to the jam of pipeline. |
Shut off the valve on the flux generator after coming off duty,wash the flux generator regularly |
| 5 |
The protection effect is unobvious |
①The pipeline is blocked
②Too much impurity in the solder flux generator. |
①Clean up the pipeline regularly
②Clean up the impurity in the flux generator regularly |
| 6 |
There is white powder in the nozzle and joints of the welding torch |
The time is too long the fluxing agent being stored in the flux generator,so the volatile offluxing agent combines with the moisture and leads to the forming of white powder |
①It is a normal phenomenon
②Pay attention to maintain and cleaning. |
| 7 |
Gas temperature changes frequently,the flame is unstable |
The gas is insufficient in purity,has too much moisture content. |
Change the gas or deal vapour by the method of machanical |
| 8 |
There is a large quantity of white powder adhering to the welded area |
①The density of the fluxing agent is on the high side.
②The fluxing agent is bad in quality. |
①Adjust the control valve of the flux generator to the ideal position
②Change the fluxing agent |
| 9 |
The gas flow of the welding torch reduce |
①The flux generator is blocked
②The flame back arrestor is blocked
③The nozzle of welding torch is blockde |
①Clean the flux generator
②Change or wash the flame back arrestor
③Dredge the nozzle of welding torch |
| 10 |
You can see bright blue flame but the fumction of fluxing agent that aids fusing is yet not enough |
①No fluxing agent
②The control valve is totally opened which makes the liquid fluxing agent deviate from the flame .But there is fog in the hose or fog rising from the flux generator,make the flame become green.
③The fluxing agent is bad in quality |
①Add fluxing agent
②Close the control valve,you may need to rotate the valve more than one cirele,then adjust the control valve to get the ideal flame.
③Change the fluxing agent |
| 11 |
Fluxing agent squirts from the welding torch |
①Too much fluxing agent is poured into the generator
②The inlet and outlet are misconnected |
①Reduce the quantity of fluxing agent in the generator to the 1/2 window position
②Reconnect the inlet and outlet. |
