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: What's the difference between a spot welder and an electric welder?

Spot welding machine, welding machine, soldering iron difference: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: 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: How can welding machine be changed into twin welding machine?

Change your electrode

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

You can use the 300W inverter

Q: Small spot welder parameters

Small spot welder parameter technical parameters are generally:Standby power 60WMaximum output current 2500A (5%)Maximum output voltage 4VMaximum output power 9KVAOutput control mode, double pulse constant voltage / constant current / constant powerOutput current range 300a~2500aOutput voltage range 0.200v~4.000vCharacteristic：1) the control accuracy is high, the reaction speed is faster, the welding quality and welding speed are greatly improved than the ordinary welding power supply2) constant current, constant voltage and constant power welding can be used to control the actual welding current directly3) the welding effect will not be affected by the power grid voltage4) high control accuracy, welding time less than 1ms, welding current 10A adjustment accuracy.

Q: Can spot welders be mobile?

Mobile spot welder is available, but not many people use it. Safety is a very important problem

Q: How do you make a simple spot welder with several 10000uF-250V capacitors?

Isn't it better to give professional jobs to professional people? Safety is the key!

Q: Is the smoke from the spot welding machine poisonous when it is welded?

Toxic, but not long engaged in occupations, occasionally nothing.

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
