1. Before installing the Electrode, be sure to lightly grease the O-ring with a small amount of silicon lubricant.
Replace the electrode and tighten it with the wrench. Do not overtighten.
2. Before installing the Swirl ring, be certain that the O-rings have been lubricated with a small amount of
silicon grease. Install the swirl ring with the bottom O-ring facing the inside of the torch. Push it into place.
Be sure to hold the swirl ring in place until the nozzle is installed to avoid dropping it into the water of the
water table.
3. Install the nozzle and finger-tighten it. Finish tightening it with the wrench. Do not overtighten.
4. Screw on the Shield to the Retaining cap and tighten by hand. Screw on the retaining cap to the torch by
hand. Make sure that it is tightened snugly; if it is loose, it can affect the shield gas flow.
