Using your CK 17 - style TIG torch is easy. First, make sure you've got the right CK 3 series (10N) consumables in place. Connect the torch to your welding machine, and you're ready to start welding. Keep in mind that this torch is rated for up to 150 amps, so don't exceed that limit. It has a 100% duty cycle at 150 amps, which means you can use it continuously under normal conditions. When it comes to maintenance, the air - cooled design helps with heat dissipation, but it's still a good idea to clean the hardened brass head regularly to keep it in top shape. And remember, the torch body doesn't come with a handle. You'll need to get the handle with the part number CKWHM separately. Store the torch in a dry place when not in use to prevent any damage.
