Q:Control principle of spot welder?

Belonging to a welding machine in resistance welding, resistance welding is divided into four forms: welding spot welding, projection welding, butt welding, seam welding. As a result of wide range of applications, the form of direct, so we are accustomed to welding machine collectively. So you ask the spot welding control principle, in fact, is the principle of resistance welding.Resistance welding is a method of welding the workpiece by applying pressure through the electrode and using the resistance heat produced by the current passing through the contact surface of the joint and the adjacent region.The physical essence of resistance welding process, is to use a lot of energy of plastic deformation and resistance to heat and the welding zone itself, so close to the lattice distance form the metal bond between the metal atom two separation performance, to produce a sufficient amount of grain in the combined surface and get the weld joint of solder joints, or. Resistance welding is a welding quality stability, high production efficiency, easy to realize mechanization, automation of the connection method, widely used in automobile, aerospace, electronics, household appliances and other fields.

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!!!

Voltage regulator is used by small electrical appliances, welding machine is not good

Q:Can ring transformers be used as spot welders?

As long as the power is enough.

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

Welding, has the switch been turned on? Is there an alarm signal?

Q:Spot welder current for a long time, small, what is the matter?

Voltage instability is the main reason

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

Basically no harm, rest assured to use.

Q:Its voltage is very small in the safe voltage range, but it produces the current is very big, I want to know that this electric current can do harm to the human body?

When the body of the current through the 0.6mA, the body will cause a tingling sensation; through the current 20mA, can cause severe pain and dyspnea; current through the 50mA ANN are in danger; the current through the 100mA Ann above, the heart stops beating can cause paralysis, heart, until death.

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

It's still bigger. You need to wear a mask

Q:12V switch power supply to battery spot welder

If the welder power supply may not be suitable, the welder can usually output 1000A-5000A current when the welder is working. This current is small.

Q:Welding four angle nuts with fixed spot welding machine, either Han or weld deformation, please help

Do you use the welding nut? That is, you must use the welding nut
