Inverter welding / TIG from the manufacturer Helix, where the inverter technology enhances the performance and durability of the machine and helps reduce its weight. The TIG method is suitable for slow welding on aluminum and stainless steel that requires detailed work and does not create splashes. It can operate continuously for 6 minutes at 150A before needing to stop to cool down. Therefore, you may need more time to melt thicker wires and make more passes on thick welds due to the low maximum Amps it supports.
