Which piece of equipment requires training for proper usage before handling?

The requirement for training before using equipment hinges on both safety and the complexity of operation. The welding machine is typically more hazardous and involves skill in handling materials and understanding the equipment’s operation to prevent accidents. It requires knowledge of safety protocols, the correct settings for different materials, and the proper use of protective equipment.

Meanwhile, equipment such as the hand truck, while it may require basic instruction for effective use, generally carries a lower risk factor, making specialized training less critical. It is important to recognize that while everyday items like an electric drill or saw may also necessitate understanding their operation, they are more commonly considered straightforward enough for basic use without intensive training.

Understanding proper usage and safety protocols for welding machines ensures not only the user's safety but also the quality and effectiveness of the welding process itself.
