Q:What is the reason that the battery spot welding stick together after welding?

Battery welder after spot welding together have 2 kinds of reasons, the welding current is too large to weld nickel plate in the welding needle, appropriate to reduce the welding current and welding time, followed by the examination of spot welder welding needle material, spot welding work in large current discharge, we need good spot welding needle material, the material has performance high strength, high hardness, high conductivity and high softening temperature

Q:What is the output current of 75KVA spot welder?

Frontal primary current 180AMax. welding current 17000A

Q:How to choose suspension spot welder

If the workpiece is relatively large, the sheet is not too thick. 0.5-2 mm, the working environment is relatively large, you can choose hanging type spot welding machine, one and split each have advantages and disadvantages.

Q:There is an old spot welder, can not see the label, probably more than 40 streams, due to voltage instability, would like to add a voltage regulator, I do not know can play a role? Consult a master to help, first thank you!!!

Cannot add! Voltage regulators can't hold water

Q:That is, welding nickel belt, that spot welder, can not be used to weld electronic components, why?I think the copper clad copper foil is too thin, want to replace with a thicker wire, I shed technology does not pass, often for appearance of a solder joint tangled for a long time

No, because the spot welding is the welding of the base material through the welding of the resistor, which will destroy the electronic components

Q:What type of welder or spot welder uses an annular iron core?

Spot welder has seen the use of C core, but did not see the use of ring iron coreIn theory, you should be able to use the ring core AC spot welding machine, but not too good around the secondary (secondary general use of copper). Pulse spot welding and energy storage spot welding machine is not suitable, because it is easy to cause the magnetic saturation!The electric welding machine itself is based on the lengthened magnetic circuit to limit the output current, so it is not suitable for the use of toroidal iron core!

Q:What accessories do you need for homemade spot welder?

The minimum configuration, a transformer. The other copper wires are on the electrode. Wait。

Q:I have a transformer capable of entering 220V 6V 12V 24V 36V capacity 1000VA low rated current 27A, I want to make it a touch welder. Do 2 square meters of small wire connector. Need to add something, want to play a few, to the points

1000VA transformer into a welding machine is too small, if it is below 0.5 of the touch sheet can also reluctantly, you touch 2 square below the head can not be used, within the thread insert is usually copper, little resistance and iron materials, how many times, you should use the large power transformer. Don't waste time

Q:How can the automatic spot welder prolong the life of the welding nozzle?

The service life of the automatic spot welder to prolong the welding nozzle shall depend on all the materials of the soldering nozzle. The welding nozzle materials are generally spot welding of beryllium cobalt copper, chromium zirconium copper, beryllium copper nickel, copper, tungsten, pure tungsten molybdenum, copper and brass and so on, you want to extend the service life of the welding nozzle, must first be clear what kind of welding nozzle material can be welded in their products, to ensure the welding quality under the condition. Then select the tip material of their own, you can focus on the good conductivity, wear resistance, high hardness materials, in addition to inspect the welding parameters and welding time, adjust to the best welding work, so you can not care for this and lose that.The double point welding current welding principle, when the two electrode pressure workpiece makes two layers of metal forming some contact resistance in the two electrode pressure, welding current from the electrode through another electrode is formed on the two point contact resistance moment of welding, and the welding current from another the two part flow along the electrode with the electrode to form a loop, and will not hurt by the internal structure of welders.

Q:How can the electric welding machine be refitted into spot welder?

Cannot be changed.Welding machine usually refers to welding rod, arc welding machine, such as BX- series AC welder, ZX- series DC welder.The welder belongs to fusion welding, referred to as fusion welding.Spot welder, the full name is: resistance spot welder. Resistance welding, referred to as: resistance welding.The work principle is different and cannot be changed.Electrode hand arc welding no-load voltage is usually at 50-85V, working voltage according to welding machine category is different, the size is different, usually between 30-45V. Tens of volts welding current small diameter welding electrode can be welded.Resistance spot welding no-load voltage is usually less than 10V, welding current from 3000A~ tens of thousands of amperes. Weld time millisecond level. By pressing, the low voltage and high current form the nugget at the pressurizing part. Achieve welding effect.
