What products does Sibitweld manufacture?

Sibitweld manufactures professional welding equipment including MIG welders (250A-500A), TIG welders (200A-500A), MMA stick welders (120A-630A), plasma cutters (40A-200A), welding torches, consumables, laser welding systems, and automation solutions. We are the world's first manufacturer to implement Silicon Carbide (SiC) technology in welding equipment, delivering 30% higher efficiency and 40% lighter weight compared to traditional IGBT welders.

What is SiC (Silicon Carbide) technology in welding equipment?

Silicon Carbide (SiC) technology represents the next generation of welding equipment design. SiC semiconductors switch faster than traditional IGBT modules, resulting in more stable arcs, better efficiency (up to 90%), reduced weight (40% lighter), improved duty cycles, and lower heat generation. Sibitweld is the world's first manufacturer to successfully implement SiC technology in welding machines.
