Using this Hypertherm drag cutting shield is easy. First, make sure your Powermax machine has a Duramax torch. Then, simply attach the shield to your hand torch. For best results, use it for 15 - 85 amp drag cutting. When handling the shield, be careful not to drop or damage it. After each use, clean the shield gently with a soft cloth to remove any debris. Store it in a dry place to prevent rust. If you buy the bulk pack of 10, keep them in a safe and organized spot so you can easily grab one when needed. This way, you'll enjoy faster cutting, better quality, and longer - lasting consumables.
