• Insulate work clamp when not connected to workpiece to prevent contact with any metal object.
• Do not connect more than one electrode or work cable to any single weld output terminal. Disconnect
cable for process when not in use.
Cylinders
Compressed gas cylinders contain gas under high pressure. If damaged, a cylinder
can explode. Since gas cylinders are normally part of the welding process, be sure to
treat them carefully.
• 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, cutting or other electrical circuits.
• Never drape a welding electrode or cutting torch over a gas cylinder.
• Never allow a welding electrode or cutting torch to touch any cylinder.
• Never weld on a pressurized cylinder – explosion will result.
• Use only the correct compressed gas cylinders, regulators, hoses and fittings designed for the specific
application; maintain them and associated parts in good condition.
• Turn face away from valve outlet when opening cylinder valve. Do not stand in front of or behind the
regulator when opening the valve.
• Keep protective cap in place over valve except when cylinder is in use or connected for use.
• Use the right equipment, correct procedures and sufficient number of persons to lift and move
cylinders.
• Read and follow instructions on compressed gas cylinders, associated equipment, and Compressed
Gas Association (CGA) publication P-1 listed in Safety Standards.
