Q:How to change the spot welding point can have the longest service life

With the electrode materials, the cost will be very high, the key in the adjustment and maintenance, setting current, welding time value is too high will definitely affect the loss; grinding is not standardized; the water is not in place; the electrode head according to the use of appropriate to increase the thickness of the welding ends;

Q:What is the harm of pedal type spot welder to the human body?

1, spot welding when there is dust pollution, ventilation is good, the problem is not big.2, the parameter setting is not good, there will be splash sparks, hot and hurt eyes, gloves, sleeves, goggles and other labor protection supplies can not be less.3, welded joints and electrode head may be scalded, do not touch.4, don't put the meat into the electrode will be crushed, unless you torture5, welding when the magnetic field is very large, so: the pacemaker with spot welding is equal to suicide.6, do not bring birth certificates, bank cards and other things that will be erased.7, with mechanical watch operation will cross.

Q:Control principle of spot welder?

You this is the equivalent of a counter current through the method, considered a record, but the conventional signal acquisition counter voltage value, you can pass the current into voltage does not exceed the value of 30V to counter acquisition equipment above, when the voltage reaches above 5V can be considered to be a high level, a number of the best. You calculate this current size range, across an appropriate resistance, by recording more than 5V times more than by the voltage of this resistance to count. The welding machinery is provided with these machines

Q:Spot welding machine has a 200KVA, not because of the full load operation (only 1/10 of its power operation) now want to take in the power distribution cabinet on a 200A, don't know if I can start immediately after starting antihypertensive use, current will have impact on the grid?

AC welding machine, the current is directly from the grid, and the power of your 200K, how much will affect the power grid.

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

Transformer, electrode, lead

Q:What should be done with welding and welding of suspension type spot welding machine?

The welding current can be adjusted properly and the welding time will be reduced. Your plate feels a little thin, so think of setting it up. It is not possible to consider the gold chelate spot welding machine, DC welding, very small splash, the sheet is not splashing, it is good for people's health. Hope to help you. Baidu can call me in Chengdu or the Southwest

Q:How can the automatic spot welder prolong the life of the welding 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 your products, to ensure the welding quality under the condition of again select the tip material that you can focus on good conductivity, wear resistance, high hardness materials, in addition to check the welding parameters and welding time, adjust to the best welding work, so you can not care for this and lose that.

Q:What is the danger of hanging type spot welding (resistance welding) radiation to the human body? The power supply is 380V after the voltage change is below 36V and produces about 10000 Amperes

Arc welding, welding, coating and base metal electrode in high temperature in the arc melting, evaporation, oxidation, condensation, soot produced a lot of metal oxides and other substances, long-term inhalation can cause pneumoconiosis. Welders' pneumoconiosis generally occurs in the closed, poor ventilation work conditions, length of service for 18 years on average about [3]. Pulmonary function test showed that exposure to welding fumes can cause the damage of pulmonary function of welders to a certain extent, pulmonary function indexes of FVC, FEV1.0, FEV1.0%, MMF, V50, V25, PEFR and [4] were significantly decreased; the pulmonary ventilation function of smoking and dust on welders may produce synergistic effect; the pulmonary ventilation function of welders damage increases as the exposure time prolonged trend [5].

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:When welding, why is the same model thickness, the same material in different spot welding machine controller welding current is not the same?

Welding electrodes are different, welding pressure is different, welding time is different, spot welder controller is different or different, will make welding current is not the same.
