The Hitachi welding inverter is made on the basis of IGBT transistors. This technique turns out to be extremely easy to operate, so even novice welders can figure it out. produces products for the private and professional segment. Inverters ensure the creation of high quality seams, regardless of which electrodes are used during the process. The technique works well with stainless steel and other problematic metals and their alloys.
The Hitachi welding machine can be connected to a constant power supply as well as to various generators as it has no special connection requirements. Everything can work from a regular outlet. The devices are of high quality, so even under high load they can function for a long time and do not fail.
The manufacturer produces universal models that can work as standard inverters, with manual arc welding, and as semi-automatic ones, using wire and shielding gas. Switching between modes is carried out using special toggle switches. The manufacturer adapts to modern realities, so many Hitachi welding machines are resistant to voltage surges, which often occur when the welding equipment is turned on and its intensive work.
Advantages and disadvantages
The Hitachi welding inverter is a modern device that has all the functions necessary for welding work. However, it has distinctive features that make it stand out from its competitors in the segment. The advantages include:
- ensuring high-quality work even with unstable voltage;
- presence of functions: anti-sticking, hot start and forced arc;
- good operation of the cooling system, which protects equipment from overheating even when used in the summer at maximum settings;
- the presence of a power stabilizer in the circuit of many models;
- ease of use;
- high-quality assembly and parts;
- compactness and ergonomics.
Although the device can be found both in private use and in the hands of professionals (which depends on the specific model and purpose of use), its cost is prohibitively high. This is perhaps the only, but significant drawback.
This is not a budget segment equipment, and the quality of the goods presented here is appropriate.”
Functionality
The main function of the devices is to weld metal. The most common functions of this manufacturer are manual arc welding, which is carried out with consumable electrodes, as well as semi-automatic welding using shielding gases and wire. They can be combined in one device or be in different ones, which depends on the design features.
A hot start helps to ignite the arc better when starting welding. This occurs due to an increase in operating parameters by 10-20% of the established ones. At the moment of ignition, it is the lack of current that prevents the arc from being ignited the first time, while this addition helps to do this in the easiest way and immediately return everything to normal when the welding process begins.
Anti-stick is another useful addition that helps simplify the workflow, as well as maintain the functionality of the device for a longer period. When the electrode sticks, a short circuit occurs, which can damage even the most powerful devices. When this happens on Hitachi equipment, the circuit cuts off the power until the electrode is removed from the sticking area.
Forced arc - if during work there are problems with the stability of the arc, which are caused by the movements of the master, voltage drops or other reasons, this function equalizes all parameters. It does not allow the arc to go out and maintains the specified operating characteristics.
The overheat protection function protects equipment from critically high temperatures that arise during operation.
Model range and technical characteristics
The Hitachi W160 welding machine is sold in a special plastic case, which can be used for transportation. The Hitachi W160 welding inverter is designed primarily for home use, as it does not have high power, and the duration of operation at maximum parameters is far from the requirements that are put forward in the professional field.
