Start up:

Shielding gas: open main valve (turn counter-clockwise)
Photo regulator tank volume (right), check output pressure (left) is set 7-12
Ground clamp: secure to worktable or work
Torch: check tungsten & hang securely on table
Pedal: set on floor
Fume extractor: position over work & turn on
Proper attire: Adjust helmet, wear gloves
Machine: turn on

Shut down:

Machine: turn off
Hot work: put in a safe place to cool
Torch: remove tungsten and sharpen
Torch: clean ceramic cup, reinstall tungsten
Pedal, torch, & ground clamp: coil neatly and hang
Shielding gas: close main valve (turn clockwise), leave regulator as is
Photo regulator tank volume (right)
Fume extractor: turn off
Clean work area: clamps away, sweep tables and floor
Return in 20 minutes for fire safety check
