Pros below: Manufacturing quality. All-metal wire feed mechanism. Synergistic control (to adjust, just select the thickness of the metal). Set for MMA welding. Modes for TIG welding. Has some cons: MIG / MAG from 50 A, which is supposedly too much for thin parts (I'll check). TIG torch must be purchased separately (I grumble, almost everyone has it). Mask included for laughter).
