Welding device: how to learn to cook for novice welders, comparison of inverter and transformer for welding

Nowadays, quarreling is the most common way to put two metal parts together. From the outside it seems, what to cook is simple and easy, but in fact the profession of a welder is quite complex and requires certain skills. There is a lot to learn and a lot to consider first, than to undertake the welding process.

For beginner welders and for professionals, working at height, compact modern welding machines - inverters - went on sale.

Apparatus for welding

The welding machine performs work using a power supply and electrodes.

There are two types of devices:

• inverter;
• transformer.

Transformer type devices are easy to operate, but have great weight and large size, strong and durable, and also very reliable. Alternating current is required for operation. Calcium fluoride or rutile fusible electrodes are used for welding. The unit has a low efficiency, and a welding seam, made using a transformer device, it turns out of medium quality. When working with this type of electric welding requires high qualification of the welder.

An inverter is an electric welding machine, which operates on direct current, in contrast to the transformer. At the input of the device circuit the incoming voltage will be converted from constant to variable, which then enters the transformer. The main difference of this type of welding is the following:

• light weight;
• mobility;
• compactness;
• well-proven device in the field;
• independence from the input voltage;
• economy.

Inverters are very economical, when using the device, the loss of electricity is ten times less, than in the operation of transformer models. The device has a efficiency of 85 to 90 percent.

You can use the inverter to connect as small, and large metal products. Inverters in our time have become a major breakthrough in the field of welding machines, old bulky transformers are gradually being pushed out of use due to their size and application difficulties. The inverter is available as a price, and according to the classification of any welder, it is enough to know the basics and principles of the welding process.

Electricity, which is consumed by this small welding machine, goes exclusively to the work of the arc itself, which directly carries out the welding process.
