Why does my Metallisation Paint Sprayer pistol backfire?
- D
  dixonmicheleAug 6, 2025
  A Metallisation Paint Sprayer pistol might backfire due to several reasons: * Leaks in the Nozzle Assembly. Inspect ‘O’ Rings for damage or loss and tighten the Air Cover. * Oversize gas holes in the Nozzle Shell. Replace the Nozzle Shell. * Incorrect Pressures. Ensure that air, gas, and oxygen pressures are as recommended. * Incorrect Nozzle parts. Check the part numbers. * Restrictions in Oxygen/Gas holes in the Mixing Block. Check oxygen and gas ports and clean them if needed. * Debris in the Air Nipple. Carefully clean the Air Nipple. * Opening the valve too quickly. Open the Valve less quickly. * Wire protruding too far forward from the Nozzle. Pull the wire back until it is flush with the Nozzle face. * Wire feeding too fast. Slow down the wire speed.

What to do if the Metallisation MK 73 Paint Sprayer coating is too coarse?

  Lauren ClarkAug 11, 2025
  If the coating from your Metallisation Paint Sprayer is too coarse, it could be due to: * Insufficient air pressure. Check the supply and readjust the regulator. * A dirty or damaged Air Nipple. Clean or replace the Air Nipple. * Wire feeding too fast. Slow down the wire speed. * The Air Nipple being jammed in the lighting position. Remove and refit the Air Nipple, ensuring it can move freely on the Nozzle. * Dirty or damaged Nozzle assembly parts. Remove and clean, or replace the Nozzle Assembly parts as needed.
