One of the most common methods of joining metal parts is a semiautomatic welding machine. This type of welding is carried out using a consumable electrode placed in a shielding gas (CO2). The gas may vary depending on the metal to be worked with and the desired result.
The semiautomatic welding machine is a power source that starts the feeder, control unit, the torch itself and the gas flow regulator. Now let's look at all the details separately.
There are two types of board or control unit :
- synergistic;
- traditional.
The first is, of course, more convenient, because with a synergistic control system, it is easy to select and adjust the mode required for operation, and thereby improve the final result - the welding seam.
There are three types of current sources:
- with step regulation (transformer);
- continuously variable (thyristor);
- with smooth adjustment (inventory).
The choice of the feeder depends on the purpose for which you purchase the welding machine. If you are planning to carry out small welding work, a two-roller machine is suitable for you. If you are planning a large industrial production, four-roll welding machines are for you. It is also worth considering one advantage of the four-roller semiautomatic welding machine, such machines can work with soft metals.
Some semi-automatic welding machines have a liquid cooling unit. For continuous loads using currents above 300 Amperes, this detail must be taken care of. It will supply and drain coolant from the burner.
