Types of welding possible with Helvi MONOMIG 186

• MIG: In MIG welding the electrode is made up of a metal wire which is also used as filler material and the unwinding of the spool occurs semi-automatically, unlike TIG welding.

MIG welding is a welding process in which a continuous electrode wire is automatically fed through a welding gun. During the process, molten electrode wire is deposited on the junction between the metals to be joined , while a protective gas, often a mixture of argon and CO2, is used to protect the welding area from oxidation and atmospheric impurities.

MIG welding is known for its versatility and ease of use . It is suitable for a wide range of materials, including steel, stainless steel, aluminum and other non-ferrous metals. This process is widely used in industries such as the automotive industry , metal structure construction , equipment manufacturing , and much more.
