User Manual & Maintenance

The Drader Injectiweld Plastic Welder User Manual is a comprehensive booklet on proper usage of the hand-held welder. It includes maintenance tips, including the following warnings and notices:

  • Compressed Air 90 psi (6.2 bar or 4 CFM)
  • Minimum: 80 psi (5.5 bar or 3.56 CFM)
  • Maximum: 100 psi (6.9 bar or 4.44 CFM)
  • Do not cycle the welder without welding rod. Damage to roller feed mechanism may occur.
  • Tip Retainer Nut must be tightened before use. Tighten during warm up and periodically during use. Failure to tighten nut may allow plastic to leak back causing damage.
  • Use a copper, or brass brush to clean away burned heat transfer compound. Clean parts make heat transfer more efficient.
  • Make sure you always use the Barrel Washer (IPAR-A-BARWSH). It goes between the barrel and the tip.
  • Do not oil the welder. Keep the compressed air dry. Always use the Drader supplied air filtration units and keep them well maintained.
  • Use Welding Rod 4mm only (standard diameter 5/32”).
  • If the Injectiweld is not being used for a period of ½ hour or more, either turn the welder off or turn it down to the lowest temperature level.
  • Plastic should be at “room temperature“ for at least 24 hours before it is welded.
  • When almost finished a roll of welding wire, remove the last remaining welding rod from the welder and start a fresh roll. This will reduce the chances of a rod jam.
  • If the welding rod does not feed, make sure the rod release knob is loose, depress the trigger then apply gentle pressure on the welding rod, pushing it into the welder. The feed mechanism will grab the welding rod and start the automatic feed.
