In the old days, welding equipment was bulky, heavy, and required special skills in use. However, modern inverters for welding are devoid of all these disadvantages. On the site you can purchase everything you need for welding – basic equipment, electrodes, protection systems and much more. However, before buying an investor, you need to decide on the main parameters of the device. Let’s consider which of them should be paid attention first of all..
What to consider when choosing an inverter for welding
Most often, welding equipment is manufactured in China or European countries. In the first case, the devices have a low price, in the second – high cost and prestige. Not always for a well-known brand, it makes sense to overpay. It is important to simply know the basic parameters that you need to consider when buying. Let’s consider them in order.

Not always for a well-known brand, it makes sense to overpay. It is important to simply know the basic parameters that you need to consider when buying. Let’s consider them in order.
Power. It must meet the parameters of the mains. If the indicator is 32A, and the wiring – 16A or 25A, operation of the inverter can cause all wires to burn out.
Availability of protective systems. In welding equipment, special power switches are used that increase the performance of the mains. If the voltage is high, they can simply burn out. Existence of special protection will prevent such consequences..
Continuous operation. The indicator reports the time during which the equipment can operate at maximum current. Well, if it will be 60% and above. This means that within 10 minutes the inverter can work for 6 minutes, and the rest 4 minutes it must rest.
Rated operational current. This is the value at which during operation of the equipment it will not overheat and work with overload. For example, when welding metal up to 4 mm thick, electrodes with a cross section of 3 mm will be needed. In this case, the optimal current is 120A. It’s good that the device has some reserve – it should be at least 30%. In this case, inverters should be considered, in the documentation of which there is a figure from 160 amperes.
Moisture and dust protection level. For this purpose, special mechanisms can be used in the equipment. Especially popular are devices with protection class IP21. This is enough for domestic use. If the indicator is higher, this affects the cost of equipment.
Extra options. They give the inverter additional functions that increase the comfort of working with it. Good to have a function «Anti-sticking», which blocks the current supply if the electrode sticks. And thanks to the mode «Hot start» the equipment will be ready for welding in less than a second. If the inverter will be used to create a vertical seam, then the function is useful «Afterburner arc».
Other parameters that should be considered when buying an inverter are suitable equipment for repair, warranty period and ease of use. Approaching with all the attention to the choice of device, you will get a reliable assistant for welding.
