Ok so I have been kinda wanting to start shopping for a mig but theres a few things I have read somewhere on here that I wanna know if is true or not. One is that you cant start welding with the wire resting on the metal. You have to always keep the wire off the metal when starting and if you dont you have to cycle the power. Also that the nozzle on it is ellectrically hot while welding. That also seems like it would be anoying having that because every time it hits the metal while welding it would stick on there.
