HELVI welding machine: choose quality and reliability

Helvi company is leader of the equipment for hobby and construction’s industry, welding machines in particular. This brand has now become an important reference point for numerous hobbyists and industry workers. The company’s strong point is not just the production of quality welding machines and accessories, but also the convenience on an economic level thanks to all its products’ great price-performance ratio.

There are different categories offered by the company, among which are inverter, tig, multi-process and wire. One of the most used is the Helvi inverter welding machine, which, thanks to its performances, makes the welding process much lighter and compact compared to a traditional one. Contrary to a normal welding machine, which is equipped with a big transformer, the latter is composed of several electric boards that considerably reduce cluttered spaces. Like every welding machine, before the use it is necessary to acquire all the individual personal protection equipment, which make the job much more comfortable and safer, such as mask for the protection of the eyes, mask to protect the airway, and protective gloves for the hands.

Functioning of the HELVI inverter welding machine

Its operation, compared to a traditional welding machine, is very easy. Normally, in a common welding machine, an integrated transformer makes the alternating current circulate, while in the inverter welding machine the continuous current is derived from an electronic circuit. This component is equipped with a potentiometer on the inside, which regulates the amperage; this tool turns out to be very useful in many situations.

Another benefit of this type of equipment is that it does not need an ignition for the electrode, like the normal welding machines. Thanks to its small dimensions and to its practicality, this device experienced a huge success both in worksites and in hobby. Another characteristic that distinguish it from the others, is its ability to melt different materials, not just metals and metal alloys, but also plastic products. Perfect for the DIY enthusiasts who want to carry out works themselves, with security and practicality.

Methodology if you use a HELVI welding machine

Like with all welding machines, it is necessary to know their functioning to conduct all the operations in a safe way without taking any risk. Crucial are the protection for the eyes, because the sparks might gravely damage them, a protective mask for the airway, because during the melting process there is a release of toxic substances, and protections for hands and body. If used professionally, it is necessary to adopt fireproof clothing, which allows preserving of the operator’s health. The working environment must also be safe, away from humidity, and be able to allow social distancing, in order to preserve other people’s health as well.

How to perform the welding

To execute a satisfying work, it is necessary to have a perfect coordination between the adding of the metal and the moving of the torch. This process has to be very accurate and targeted.

Its operation needs great experience, because it is necessary to consider the intensity of the sprinkles, the preparation of the Tungsten for the ascending and descending current in relation to the background current, to the pulsation, and, lastly, to the frequency of the electric current. Before engaging in its use, it is always appropriate to conduct sample tests on scrap metallic parts.
