Line 29:
** Using an auto-darkening welding mask
** Suitable settings on mask (9-11, 12 maybe - start at 10 and adjust)
*** Testing visors before use
*** Any setting will save your vision, you're just adjusting for best visibility
** Shouting "Eyes"
* PPE - Overalls, stout shoes, gloves, mask, dust protection when needed, Cover all exposed skin or you'll regret it!
Line 141 ⟶ 143:
** Types and their suitability
*** 2% Thoriated (Red Tip) - DC Welding on steels only, radiation danger
*** 2% Lanthanated (Blue Tip) - Universal, can be used on all metals and polarities, recommended for normal use
*** 2% Ceriated (Grey Tip) - DC use on thin materials, excellent arc stability at low powers
Line 158 ⟶ 159:
* Welder
** Checking correct polarity, making sure earth lead is connected to work
** Check tightness of connectors, they'll catch fire if they're loose!
** Plug in welder but don't turn on yet. Directly plug in, never use extension leads
* Gas

Depending on how things are going and the amount of time available the induction can stop here and allow the inductees to practice welding until they're comfortable with reflow and filler beads. The induction can resume on another day to complete the training on how to actually join metal together. If so the "Shutting down and cleaning up" section below should also be covered.
