Line 34:
* Arc-eye hazard to you and people around you
** Using an auto-darkening welding mask
** Checking masks with a strong light source
** Suitable settings on mask (9-11, 12 maybe - start at 10 and adjust)
** Shouting "Eyes" if there are other people around
Line 70 ⟶ 71:
* Clean up weld area - be aware of burning paint
* Clean area for earth clamp
*
** No bevel on thin materials
** Regular 2/3rds bevel most of the time
**
** Multipass and double sided welding are options
|| Proper preparation is necessary for good welds, cover bevel patterns for other weld types later

Line 120 ⟶ 122:
** Resting your other hand on something to use as a guide
* How the pool forms (Only cover dip transfer)
* The pool wants to move, you need to just keep pace with it
* Keeping the wire aimed at the nose of the pool
** Further towards the tip of the pool = fast move, thinner bead, less penetration
Line 142 ⟶ 144:
* Arc won't strike - Ground clamp not connected
* Weld moves around erratically - too much gas or influence from holding magnets

Line 194 ⟶ 196:
** Flap discs will tidy up welds that are good to start with
** Grinding discs will remove messy welds quickly
* Shutting off the gas
*
* Sweeping up and putting everything back where it belongs
* Working out your total weld length and paying for it
Line 204 ⟶ 206:
| Final thoughts ||
* This has only been an extremely brief over-view of MIG welding
* Do not expect your joints to be structurally sound or pretty until you have
* The sMIG feature is providing you a LOT of help on this welder, if you switch to a welder without sMIG you may find things a lot harder
* If you want to weld aluminium or magnesium alloys, Stainless Steel, Brazing or other techniques then you can look at [[Tools/TIG/induction#level2|TIG level 2]] or [[tools/mig/induction#level2|MIG level-2]] inductions although it's not compulsory to do level-2 inductions if you've already done the relevant level-1 inductions and if you think you can manage these techniques without further help
