This is the content required for an introduction to our welding transformer - reading this does NOT replace the mandatory session with a tutor! It will make it a lot quicker though ;-)

Let's begin! First off, make sure you have read the machine's <MANUAL>.

Safety

Dangers

  • extreme heat
  • very bright arc
    • light damages eyes
    • UV radiation burns exposed skin
  • splattering molten metal
  • exposed electricity (how bad? max 60 V, 100+ A)
  • toxic fumes (ozone, flux, ..?)
    • galvanized steel (verzinkter Stahl) generates ????

Precautions

  • wear proper personal protection:
  • immediately stop if anything seems to be wrong with the welding helmet
  • grind away any surface coatings (e.g. galvanization, paint) before welding, they would generate harmful fumes or at least obstruct your weld
  • take care of good ventilation - our welding enclosure is open at the top but that might not be enough for long sessions

Suggested Reading

Besides these safety notes, you should read our page about welding electrodes and <...>

Demonstration

The tutor will show you these steps in detail:

  • set up your work in the welding enclosure
    • red curtain far away
    • close gaps, e.g. with spring clamps (long-term solution needed!)
    • bring a light with you, if necessary
  • try striking an arc and depositing metal on a scrap piece (e.g. in the shape of your initials)
  • joining two pieces(?)
