Welding Process: The TB-250 is primarily a Manual Metal Arc (MMA), or stick welder. This is a versatile and common welding process that uses coated electrodes to join metals.
Inverter Technology: It uses IGBT (Insulated Gate Bipolar Transistor) inverter technology. This modern technology makes the machine significantly lighter, more compact, and more energy-efficient than older transformer welders. It also provides a stable welding arc, which is especially helpful for beginners
