Proper Eye Protection

Plasma cutters emit strong uv and ir rays, which can permanently damage your eyesight if you’re not careful. Thus, it’s crucial to wear proper eye protection. Invest in a high-quality pair of glasses or goggles with a shade level of 5 or higher to protect your eyes from harmful rays.

Use Of Protective Clothing

Protective clothing is a must-have when operating a plasma cutter. Welding gloves will protect your hands from sparks and hot metal, while flame-resistant clothing like leather jackets, pants, or aprons can prevent burns from any plasma spray. Also, consider using earplugs to safeguard your hearing.

Safe Handling And Storage Of Equipment

Proper handling and storage of a plasma cutter can prevent accidents, ensure longevity and save money. When handling the equipment, avoid direct skin contact with the plasma cutter’s torch or cable. Instead, use insulated pliers to move the torch or handle the cable.

When storing, ensure that the equipment is in a dry and cool place to prevent damage to the tool’s delicate components.

Setting up a plasma cutter can be dangerous if safety precautions are not taken seriously. By following the guidelines mentioned above, you will not only protect yourself but also ensure that your plasma cutter operates efficiently. Remember, safety comes first, and always follow the manufacturer’s instructions when setting up the tool.
