Welding machine DC - compare with competitors

DC welding machine - the distinctive features

There are many types of welding machines, among which the most famous are: welding mechanical device using a consumable electrode;equipment for argon-arc welding consumable electrode;welding using flux automatically consumable electrodes.In addition, there is a generator for welding, transformers, inverters, devices for spot welding.For every type of metal electrodes are provided for well-defined.

on the device for the device to work with DC is much more complex unit AC, because it for the output DC voltage is set with a diode rectifier or thyristor bridge.However, the power of the welding machine output significantly less consumption due to its drop at the rectifier.

In other words, the efficiency of it is low, and this is a serious disadvantage in terms of energy savings.However, thanks to a stable arc and the opportunity to work with a variety of metals, it could be classified as professional equipment.

welder AC - what are its characteristics?

much cheaper previous sample AC welding machine , also working with consumable electrodes.It is well suited for use with ferrous metals, allows welding of overlapped and butt.

When using this welding machine 220 are the operating voltage, but it is idling may vary depending on applied the electrodes, which can be both calcium fluoride and with rutile.The device is simple to operate, provides a smooth adjustment of the current strength, which depends on the work electrode.

This transformer welder can be successfully used both in the home and in the factory.Electric welding devices are designed for operation from 220 or 380 volts, and accordingly are called single or three phase.Depending on that changing the scheme of connection of welding wires.

single phase welding machine is connected by adding one of the welding wire to "phase", the other - to the connector "neutral", and the third - to the ground "zero".Otherwise, it connects a three-phase welding machine.The two ends of the welding cable connected to any two "phases", and the third - to the protective "zero."

should be noted that if the use of the welding machine 380 V, it is considered more potent than connect to the network at 220 volts, but not the only way to increase productivity.

Inverters - increases power welder

Until now, we have considered the welding machine, which is used in conventional power transformer as the input voltage converter.It is to them and determined by solid size and heavy weight of this type of equipment.However, it is reliable and inexpensive.

But there are other types of devices that are used in so-called inverters as an inverter - semiconductor amplifiers.Small size and weight made them perhaps the most popular type of welding machines.

At the level of efficiency, reaching 85%, the unit works with different metals, ensuring high-speed, quality and precision welding.Inverter devices have different power and can be connected to networks 220 and 380 volts.
