How do I safely handle compressed gas cylinders used with this welder?

Protect compressed gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flames, sparks, and arcs. Install cylinders in an upright position by securing to a stationary support or cylinder rack to prevent falling or tipping. Keep cylinders away from any welding or electrical circuits, and never allow a welding electrode to touch any cylinder. Always turn your face away from the valve outlet when opening the cylinder valve.
