MIG/MAG

What is OTC MIG/MAG Welding?
OTC MIG/MAG welding is an electric arc welding method that uses a shielding gas to protect the molten metal from atmospheric contamination. The main difference between the two lies in the type of shielding gas used.
MIG (Metal Inert Gas):
Uses an inert gas such as argon or an argon-helium mixture, suitable for non-ferrous metals like aluminum and copper.
MAG (Metal Active Gas):
Uses an active gas such as CO₂ or a CO₂-argon mixture, ideal for ferrous metals like carbon steel and stainless steel.

PLASMA

Plasma welding is particularly beneficial in applications where high welding speeds, deep penetration, and minimal heat-affected zones are required. It is commonly used in industries such as aerospace, automotive, and manufacturing, where precise and high-quality welds are crucial. By enabling keyhole welds and offering better control over the welding process, plasma welding by OTC provides an advanced solution for achieving accurate and reliable welds in thin and thick materials.
