Daily Maintenance - Injectiweld - Drader W30000 Instructional Manual

11. Daily Maintenance – Drader Injectiweld
A well-maintained welder will give you years of service. Follow the steps in this section to
take care of your welder.
Compressed air should be as dry and clean as possible. Use the air filtration system
supplied with the welder. Use of an air compressor with a dryer / dehumidifier in is
recommended.
Use heat transfer compound frequently. Heat transfer compound makes it easier for the
barrel heat to transmit to the tip. Apply the compound at every tip change or every 8 hours of
operating time.
Use a copper (or brass) brush to clean away burned heat transfer compound. Clean parts
make heat transfer more efficient.
At the beginning of each shift (or every 8 hours of welder operation):
Turn welder on and bring up to heat.
•
Turn welder off, unplug it from the electrical socket then wait 2 - 3 minutes. (This allows the
•
aluminum barrel to shrink smaller than the steel tip nut).
Remove tip nut, tip and barrel washer. Be careful – they will be very hot!
•
Using copper or brass brush, clean the old heat transfer paste from the tip nut, tip, barrel, and
•
barrel washer.
Apply a new layer of heat transfer compound to the tip, barrel, and barrel washer.
•
Reassemble the welder by placing the barrel washer onto the barrel first. Then place the tip onto
•
the barrel, followed by the tip nut. Use the tip nut wrench and hand tighten the tip nut. Do not
tighten the nut too much.
Plug the welder in, and then turn it on. Bring it up to the set temperature, and then commence
•
welding.
Make sure the tip nut is snug periodically throughout the day.
