Q:What kind of metal is the spot welding machine head?

Copper, zinc and aluminum alloys with high melting point

Q:Can ring transformers be used as spot welders?

The theory is OK, but the ring transformer power is too small to be suitable, and it is recommended to use E transformer or C type transformer

Q:Suspension welding machine welding, continuous welding a few trips, the trip welding is not firm, do not discharge when the action is normal, why is this? Seek expert advice.

Current should be checked,

Q:I used the Zhenjiang Seiko welding

There is the reason of weld spot welding welding parameters did not set, the first parameter test, after passing the test procedure as laid down in the production process, in accordance with the procedures.The welding parameters include 1. compression time, 2. welding time, 3. maintenance time and 4. rest time. But there are two important parameters: one is to set the appropriate electrode pressure, to ensure that can compress the workpieces to be welded; the other is the set welding current to the right, it can guarantee the molten metal to be welded. On this basis, the above four process parameters adjusted, you can firmly welded.

Q:How to adjust the spot welder?

Adjust the current, the welding time and the contact pressure according to the sheet thickness.

Q:Ask the spot performance problems, we have only one spot welding electrode and welding head, is also the same time only a welding point. If I turn on the electricity

Absolutely! On the one hand, welding defects may occur, on the other hand, it will cause great difference in the current of welding machines.

Q:When the spot welder is in use, the voltage of the line will be higher and lower. What can be done to solve it?

The single-phase AC spot welder should be used. The single-phase power supply of AC spot welder has destroyed the balance of power grid and seriously affected the normal operation of other power equipment. The inverter type spot welder is supplied by three-phase power supply, and its operation does not affect the three-phase balance of the power grid.The power factor of welding machine is an important index that affects the utilization ratio of power supply equipment. If the power factor of welding machine is doubled, the requirement of power supply capacity will be reduced by 1/2. Because the resistance welding machine outputs is the low voltage, the big current. Therefore, the inductance of the secondary circuit of the welding machine is obvious, so that the power factor of the AC resistance welder can only reach 0.3~0.5. The inverter type resistance welding machine outputs DC welding current, and the power factor of welding machine can be as high as 0.95. Therefore, the requirement of the power supply capacity of inverter type resistance welding machine is less than that of the AC welding machine of the same capacity as 1/2.

Q:What's the difference between a die laser welder and a spot welder?

Laser spot welding is current through short circuit two electrode moment and became the temperature and pressure are very high, the steel is melted, will produce crystallization during the cooling process, the two plates together, the advantage of this method is to make a lot of layer steel plate welding, but also combined however, because of deficiencies are not in good control in the welding process of generating heat and pressure, so after welding steel plate in cooling time takes longer, it is easy to change the thermal stress, it is in order to avoid the occurrence of thermal stress change and reduce its pressure and heat it is easy to generate welding penetration status.

Q:315 how can the electric welding machine change the spot welding machine? How successful is it to weld the heavy workpiece?

Our company specializes in producing various types of welding equipment, if necessary, you can contact me, contact information can see my information.

Q:18kw the small electric welding machine changes the original function of the spot welder. It needs more thick wire to go around the secondary coil

With 2.5--4 mm or so iron wire, secondary coil with copper sheet folded into 1 cm thick, 4 cm wide, with good insulation material, made after, installation and use.Mainly according to the welding material, thickness, material, the distance between the two welding points to determine.The greater the thickness, the greater the current and the greater the line;To the current high melting point material, conductive good, line to rough;The distance between the two welding points is close and the line should be rough.The closer the primary to the secondary, the smaller the leakage and the greater the current. If the secondary winding in the primary current (large short-circuit current) can be leakage of small welding characteristics is not soft, like ordinary transformer output of sixty volts, but also when the welding characteristics, not good, not good.The number of turns on the column at the secondary; the greater the current. Want to increase the current, the secondary to the primary side here to reverse point, the total number of turns unchanged, plus a fan. Plus secondary turns can be, but the output voltage is not too high (<70V), the current is large, may not be easy to use
