Certification Process

Step 1) Watch these videos prior to requesting use of the welder:

2) Request hands on training from a person already certified

3) Hands on training

   a) demonstrate competency to safely turn on and off welder (also attach tips/outlet plugs etc)
   b) demonstrate competency welding bar onto existing certification bars (both tack and finishing welds)
  

Safety Rules

  • Do not use the welder if you have not had proper training.
  • Never use the welder without a second person present to act as a fire watch. [Is this still a requirement?]
  • After using the welder:
    • Stay at the Hive for at least an hour to be sure that nothing is smoldering.
    • Sweep / vacuum floor debris at least around the area you were welding
    • Double check that all gas supplies are fully shut off

Care and Feeding

The welder itself is very low maintenance. (outside of tips, collets and consumables) According to Miller, the welder we have is an IGBT based design and is pretty much a hoss. It is also the series of welder that is their primary product line at this point. The main weakness that they mentioned was metal dust building up inside the case in "very harsh environments, like places with half an inch of aluminum dust on the floor." Regardless, they recommended opening the thing up and blowing it out with shop air once a year or so. If you happen to perform such maintenance, send a message to the google group or otherwise communicate with your fellow Hive members to let them know.
