How to use the electric welding machine
26 Sep 2021
1. After connecting the power cord and confirming the input voltage, select the corresponding voltage. 2. Turn on the main power switch, and choose the welding time and current according to the ambient temperature and pipe diameter. l Welding machine operation steps Get ready for work-connect the input and output wires-select the input voltage-turn on the main power switch-turn on the work switch-set the heating time-adjust the current to the reference value (slow adjustment) start welding-after the time is up The buzzer sounds and automatically cuts off the power-turn off the work switch-the current adjustment knob turns-remove the connecting wire plug-cool down according to the specified time-check-the end of the work; (Note: The input voltage must be selected before turning on the main power switch) 3. Problems in the construction of steel belt reinforced spiral corrugated pipe 1. The quality of the pipes is poor, and the construction party is brutally working. In the production pro...
Operation steps of electric fusion machine welding machine
18 Sep 2021
1. After the preparation work is over, turn on the operation switch, carefully adjust the working current and start welding. 2. For any reason, when the electric welding machine stops working in the middle, the timer will record the time of current passing. Press the rst key to reset and re-operate) 3. Make preparations, connect the wires—turn on the power switch—set the voltage and time—turn on the operation switch—start the timer—adjust the current to the set value (slowly adjust) and start welding—when the set time is reached, the buzzer sound Automatically cut off the power when the device sounds-turn off the operation switch to OFF, and the current knob returns to zero-take off the connecting wire clip-cool down according to the specified time-check-the end of the work. 4. The welder will automatically power off when the voltage is too high or the current is too high. Therefore, when judging whether the welder is working under normal data, just turn off and then turn on the power ...

1. Product components: 1. Electric heating tape 2. PE glue stick (need to purchase and use) 2. Construction tools and accessories: electric welding machine, stainless steel buckle, U-shaped clamp, woolen buckle, rubber hammer, Insulating gloves, wires, surface thermometers. 3. Operating procedures: 1. Put the two pipes to be constructed off the ground and align them horizontally. 2. Remove the dirt, moisture and other debris sticking to the surface of the pipe. 3. Use woolen buckle tape to wrap the electric melting tape on the connecting part of the pipe and wrap it tightly, and place the end with the terminal on the lower layer of the overlap. Make sure that the joint of the pipe is located in the middle of the electric heating tape. 4. Wrap the stainless steel buckle on the electric melting tape and fasten it with U-shaped clamps, insert the PE glue stick into the joint where the electric melting tape is overlapped, and tighten the stainless steel buckle so that the electric melting ...
How to select a straight single-seat quick-opening valve
27 Aug 2021
Caliber calculations are generally not required for straight-through single-seat quick-opening valves, but when it is close to the equipment behind the valve, in order to prevent the high-pressure medium from impacting the equipment when the valve is quickly opened, the caliber calculations must be performed on the straight-through single-seat quick-opening valves. Methods as below: Before choosing a straight-through single-seat quick-opening valve, you must understand the detailed process parameters and control requirements, and make a preliminary judgment based on the process parameters and control requirements whether you can use a straight-through single-seat quick-opening valve. If you can choose a straight-through single-seat quick-opening valve, then Perform detailed calculations of flow coefficient, noise and unbalanced force according to the process parameters, and finally select the detailed configuration of the valve according to the calculation results. The calculation and ...
Significance of corrosion protection for steel pipelines
20 Aug 2021
Corrosion of steel pipes is widespread in all sectors of the national economy and national defense construction, which has brought huge losses to the national economy. It also caused great difficulties to production and life. Steel pipes are corroded all the time under natural conditions (atmosphere, natural water, soil) or man-made conditions (acid, alkali, salt and other media). A spontaneous wasteful consumption. The root cause of the steel pipes is that they are in a thermodynamically unstable state. Under the above conditions, they will return to their original relatively stable state. Generate iron oxides and carbonates. Or converted to soluble ions. This process is the corrosion process of metals. According to statistics, my country's annual steel output is 160 million tons. More than 60 million tons are lost due to corrosion every year. It is almost equal to the annual output of Shanghai Baosteel General Iron and Steel Plant. Corrosion is not only a waste of steel resources, bu...
Precautions for capacitor welder portable plastic extrusion welder

Special note for welding machine: 1. Use the sixth gear of the fan to heat for 10-12 minutes to feed and work, and use the "D" or "E" gear for the main engine speed. 2. When the main engine stops working (when the worker is resting), the fan must be turned to the low position, and it is strictly forbidden to continue heating in the high heat position. Otherwise, since the heat cannot be dissipated, it will cause serious damage to the fan. 3. Before stopping use, the fan must be turned to the "O" position, and the cold air must be blown for 3~5 minutes to discharge the residual heat before turning off the fan. 4. When working continuously for three hours, the machine should be blown with cold air for 5-10 minutes to cool down, and then restart the work. 5. It is strictly forbidden to rotate the main engine and feed the welding rod when the heating time is insufficient, and also not to heat for a long time, otherwise the fan may be easily damaged. 6. When the hot air moves with the weldi...
