Types of welding possible with Helvi MONOMIG 186

• MIG: In MIG welding the electrode is made of a metal wire which is also used as a 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 fed automatically through a welding gun. During the process, the molten electrode wire is deposited on the joint between the metals to be joined , while a shielding gas, often a mixture of argon and CO2, is used to protect the weld 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 automotive , structural steel construction , equipment manufacturing , and more.
