Power Tools
Power tools such as reciprocating saw, angle grinder, portable band saw and chop saw are useful when cutting and fitting metal parts to be welded. A drill press and metal cutting band saw are also useful tools for welding. All power tools must be properly grounded to prevent accident shock. Even if a slight tingle is felt while using the tool, stop and have the tool checked by a technician. Power tools must also not be used with excessive force or allowed to overheat from incorrect use.

Hydrogen
Yes this is the gas that allowed the Hindenburg to float through the air and ended up bursting into flames. But, used properly it is a perfectly safe gas.
Hydrogen is the lightest of all gases and Hydrogen comprises 98% of the known universe. Colorless, odorless, tasteless, and nontoxic, hydrogen exists as a gas at atmospheric temperatures and pressures. When cooled to its boiling point of -423F (-253C), hydrogen becomes a liquid and all other gases, except helium become solids at this temperature.
Hydrogen is flammable and burns in air with pale blue, almost invisible flames. In its gaseous form, hydrogen dissipates quickly. These unique properties call for strict safety measures in hydrogen use and storage.
Hydrogen has many uses from arc welding shielding gases to fuel cells to rocket propellant. Other uses include petroleum refining processes, chemical processing of plastics, hydrogenation of food grade oils, protective atmospheres for metal production and plasma welding and cutting operations.
