Q:What is the electrode of mobile spot welding machine? Is it copper? What's more, SCR?

1 beryllium cobalt copper or chromium zirconium copper.2 general suspension type spot welder has a certain range of movement, power more than 125-250KVA, SCR 300-800A range.There are 3 integrated welding machine, welding tongs and integrated power transformer, 25, 40, 60KVA, 80-150A, scr.

Q:Spot welder can weld several points at the same time

Multi spot welder is usually a transformer double winding, one side double points can be welded 4 points, redistribution is another.

Q:Without welding spot welder welding head is what reason?

There are quite a few reasons. Mainly includes the following aspects: 1, 2, welding material; welding structure; 3, welding material structure of the workpiece; 4, spot welding power supply technology level, such as the discharge stability, welding time adjustment; 5, the maintenance of spot welder welding head grinding, including methods and frequency. Maybe these. The 1-3 point is decided by the welding material, structure, welding effect and so on. Generally, the workpiece is fixed, and the material and structure are right. So there is nothing to change. Fourth consider using inverter DC welding machine, energy concentration, welding stability, short cycle time, the long-term benefit of welding head life. Fifth, the formulation of standard grinding, correction frequency and method of guidance, how many points welding, grinding once, with what grinding and so on.

Q:What is the price of a general suspension type spot welder?

2-3, the key is power, and some power supply 4-5 ~ ~ ~ with waveform control ~ ~ ~ digital display ~ ~ ~!

Q:Welding two pieces of stainless steel by spot welding, which spot welder is the best? AC, DC?What is an inverter type medium frequency spot welder?

You see how thick stainless steel and stainless steel, AC welder / welder / welding inverter welding can be done, see you on the requirements of the degree of the welding quality is high. If you require solder joint appearance, stable welding, welding inverter can be used only if required, meanwhile, a high degree of oxidation of the solder joint is not required. AC welder / welder can be suitable for you.

Q:What is the 25KVA spot welder?

When the 25KVA spot welder is in full operation, it needs about 17KW power on the press. That's enough.

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.

Problems of the external power grid! Look at the power rating of your total power supply. It is estimated that the instantaneous current is too high during welding!I hope I can help you!

Q:Can 220V drive it?

First of all, they all belong to the category of welding welding, but the essence is different, first, by a large current through spot welding is the welding workpiece, and the workpiece has resistance to melting heat generated or molten state to give a certain pressure to achieve the purpose of welding, so it is also called a resistance welding, belonging to the pressure welding, so it is very clear, the welding material must have resistance, which is a prerequisite, 220V can be done, it depends on the transformer. Second, gas shielded welding, as the name suggests, is a need for gas protection and welding, arc welding. Then from the above we can see not hard, spot from the process is simple, does not need any external add accessories, achieve the purpose of welding, and welding is required under gas protection welding, some will wire filler, mainly depends on your products and welding. Hope to help you.

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

It all depends on all the material in the solder

Q:My spot welding is 0.4 mm iron net, in the process of use, always not scheduled trip, do not know what is the matter, please master advice.
