Should the DC arc welding machine be equipped with electricity saving, shock proof and leakage protector?
To be on the safe side, it is necessary to install a ~ ~ ~ at least you can have the effect of electricity saving, you can go to see the "Wei Wei" brand welder protector, very good use
DC arc welding machine needs electricity saving, shockproof and electric leakage protector;AC DC arc welding machine is a kind of equipment consisting of moving iron core type transformer, rectifier, reactor, switch and other main components. By changing the clearance of the moving iron core, the current stepless regulation is realized.Features and usesThe welder has the advantages of convenient operation and maintenance, small noise and vibration, etc..Can be used as high carbon steel, alloy steel, copper and cast iron and other technical requirements of welding.
In principle, all electrical appliances need to install anti electric leakage switches (especially metal shells, electrical equipment) at the power input terminals, and the same with the welder.If the anti welding output of electric shock, you don't have to worry about this, on the market in the sale of the DC welder basically has the electric shock prevention function (VRD), the anti shock function after opening, the welding output load is generally not higher than 20V, two hands and two are positive and negative contact welding output terminal, there will not be any shock feel very safe. You can buy Welding machines with this function.As far as energy saving is concerned, it is only when the electric welding machine does not work for a long time, turn off the power supply to save electricity. Now with the inverter DC welding machine, transformer AC welding machine compared to old-fashioned, no-load loss is much smaller, if only a short period of time without welding, no need to put what sort of economizer, if it is a long time without welding, mind you directly off the welding machine.
