Overview 7 Vido best welders: how to choose a rating

Welding - process for producing permanent connections. It is based on establishing close interatomic bonds at the local heating area joining materials.

Welding is used for operations with metals, polymers, ceramics. Creation of the heating zone is carried out by welding machine.

How to choose a welding machine

The unit chosen for specific tasks, therefore, is entitled to such criteria:

• Have the necessary capacity. The main index - the current.

With increasing power parameters increases the ability to handle thick workpiece (up to 6-8mm), apply electrodes Larger diameters (up to 4-5 mm) to use a long continuous operation, increasing a share unit.

• mains input voltage. 220 or 380 V. The latter figure is typical for industrial facilities. home use The unit must be protected against power surges.

The range in which the device is stable running is 180-240 V. Approaching 210-230 V value indicates that the device is designed to operate in the "ideal" conditions. Such designs better get round.

• Indicator "idle" course. Determined by the voltage value at which the lights steadily supported and electric arc. Selecting appropriate to do for maximum performance.

For the transformer - 80 V, the rectifier - 90 V, the inverter - up to 40-50 V.

• continuous welding mode. Expressed as a percentage. The figure of 40% means that the operating period lasts for 4 minutes, followed by a break for 6 minutes. Score is based on the current strength.

• The functionality of the unit. Ability to work in the gas-shielded, non-ferrous metals and alloys, the extended load range.
• Working temperature. Determined by the manufacturer. The wider the range, the better. assembly is quite suitable for household tasks to run when t = - 5 - + 40 ° C.
