The inverter welder is now very light and very environmentally-friendly.
The welding machine adopts inverter technology. It's all electronic components.
There are many protective functions in the circuit. So it's safe to say that the inverter welder is safe. But you didn't use the welder. That's not very good welding.
The welder USES the high temperature arc to melt the solder and the welding material on the welding electrode in the instantaneous short circuit, so as to combine the object with the contact.
