Q:Spot welding when there is no current, what is the matter, ask the experts to help! Thank you Online, etc.!

There is something wrong with the control circuit.

Q:Welding spot welding is not firm, the beginning of welding is possible, to the welding after 50~60 pieces will appear shaky, partition time will be good, how to adjust?

After welding the 50~60 parts of the resistance spot welder, the welding is not stable because of the following:1: welding capacity is too small. Continuous high current exceeds the rated capacity requirements of welding machine, welding machine overload leads to insufficient welding current, weld lead caused by unstable welding.2: welding machine rated output welding current is too low. According to the workpiece material, thickness, welding machine rated output current, machine capacity and other factors, choose the appropriate welding parameters, welding pressure and welding process.3: welding machine load rate is too low. It can reduce the working time of welding machine and increase the time of welding machine break. Of course, replacing high-power welders is the only solution to the problem.4: welding loop bad contact. Lead welding after a period of time, at the junction of heating workpiece. Check loop contacts and secure securely. Click or other contact points appear oxidation, timely cleaning, polished clean.

Q:The capacity of single spot welder is 160KVA, which is six units. How much cable should be selected for main circuit?

Enough, because the spot welder is working instantaneously,

Q:How can the spot welder adjust the relationship between welding strength and each data?

The main adjustment parameters of the spot welding machine are current and power time. Other preload time, maintenance time and intermittent time are not very important, but only some auxiliary parameters;So with the plate thickness increasing need to increase the current, and increase the current way is generally used for regulating voltage mode (resistance under a certain voltage, the higher the current greater), or constant current state of increased power on time, and can also increase the amount of heat input, so as to obtain good welding effect;Spot welding is generally divided into two kinds: hard specification and soft specification. Hard specification means high current + short time. Soft specification is small current + long time

Q:What harm does the factory spot welder work to people?

The first welding has a high current through the formation of a strong magnetic tddhj field, second beryllium bronze electrode after heating micro radiation, consider it, but there will be no big question

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:Our company is the production of mobile phone antenna, the antenna is composed of each section of small shaft assembly, a small shaft is connected by tubes with pin and connected together, the problem is due to the shaft diameter is relatively small, the pin diameter is smaller, the pin will be riveting is not strong, so I want to use it directly to spot welded together, do not know who can recommend a more suitable for our company specifications of spot welder. The diameter of our company's pin is between 0.6mm-1.2mm. There are recommended best. Please specify the performance, price and so on. Thank you all for the good plus 100 points as compensationThe pipe head hole size and outer diameter are 0.9 and 0.7 respectively. It is necessary to use spot welder to weld him to the pin. The time is urgent. I hope someone who knows the matter will contact me immediately

Send some work. I'll try the welding below

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?

1, the current and voltage parameters do not match well;2 、 the wire feeding is unstable;3 、 the quality of welding wire is poor;4 、 dry elongation is too long during welding;5 、 the barrel is blocked or the welding torch is too long and bent too much;6, wire feed wheel wear;7, the wire feeding force is not enough or send wire motor failure;8 、 the control cable has short circuit or bad contact;9, welding cable and ground cable is too long or too small, the contact is not good;10 、 welding machine internal plug-in contact is bad or parts damaged;11, welding input cable is too small or too long;12, welding machine input voltage fluctuation is too big or lack of phase.The stability of welding pressure is an important condition to achieve high quality welding. In AC resistance welding, the strong welding current causes the electrode arm to be interfered by alternating electromagnetic force, which leads to the instability of electrode pressure and influences the welding quality.The medium frequency variable resistance welder outputs DC welding current with little ripple, which will not affect the stability of electrode pressure, so it can be finished with smaller welding pressure.

Q:Is it harmful to eyes to work in battery spot welder?

Battery spot welding machine working principle is low voltage about 1 volts, high current discharge resistance welding machine, in the work will produce sparks, sparks no harm to people, wearing glasses is OK, no problem, please rest assured! Thanks for your reference

Q:Working principle of spot welding machine

A strong current (usually above 10 thousand A) through a secondary circuit, instantaneously produces a large amount of resistance heat at the point where welding is needed to fuse the metal and form a solder joint. Geneo port good spot welder.
