Electrode (MMA): Creates thick and strong welds without the need for an external gas supply, making it ideal for outdoor welding.
TIG: Slow welding for detailed work on aluminum and stainless steel. Requires experience and connection to an external gas cylinder. Does not create "spatter".
Inverter: Offers greater efficiency and helps reduce weight.
IGBT: Insulated Gate Bipolar Transistor: Allows the conversion of direct current (DC) to alternating current (AC) or the output of direct current to a higher or lower intensity.
