Welding voltage controls the arc length, the gap between the molten weld pool and the wire filler metal. Typical arc welding uses 12-36 volts, while striking an arc requires 50-100 volts. This voltage range ensures effective welding and maintains safety standards in processes like SMAW, GTAW, MIG/MAG, and SAW. Understanding the basics of arc welding … Read more

Two types of AC arc welding machines are transformer-type and inverter machines. Transformer-type welders use electromagnetic induction for welding, while inverter machines offer high efficiency and better control. Each type serves different welding needs effectively and efficiently. Inverter-based machines utilize advanced technology. They convert AC power to DC, resulting in better control over welding processes. … Read more
