Sorry, we are still working on the Spitfire section, this is part of a welding page I am trying.
Most welding in auto shops is done fairly quickly as they tend to be small jobs or repairs. The operator tends only to wear gloves, (FIG 1) a long sleeved jacket buttoned up to the neck, and a full helmet (FIG 2) fitted with the correct lens. For most electric welding a #10 lens is suitable. If SMAW (arc welding) do not wear contact lens revert to glasses as you will experience serious problems with the contacts. In some cases if access to see the weld is difficult due to the size of the helmet a pair of goggles (FIG 3) can be fitted with the #10 lens and used. But with any electric welding note that if using goggles this leaves the skin on the face exposed to the ultraviolet rays from the welding arc. Any exposure over a few minutes will burn your skin, and no it's not like sunburn. The same applies to electric welding without gloves or your arms being covered. If welding for any length of time as on collision repairs take the time to dress properly. Try to avoid turn-up in your pants and wear coveralls. If welding overhead tape up your breast pockets and fasten your coveralls to the neck. If sparks or slag enters any of these places they will burn your skin. Paper in your pockets can also be set on fire. Setting fire to your clothing is not amusing. Finally make sure your coveralls fit over your boot tops (FIG 4) and laces, as again any sparks or slag entering your boots will burn you. Needless to say if you have just spilt gasoline over yourself don't start welding. The same holds true for any flammable substance on your clothing or coveralls. If using the oxyacetylene for heating this amount of protection is not necessary just make sure you wear goggles or tinted safety glasses (FIG 5) with side shields. Turn the flame off when you have finished don't put it down still alight to one side.
Can be a bit of a problem in the automobile or body shop environment as the welding is hardly ever in a fixed position or place. A suitable ventilation system cannot be installed for use in the building. If welding in a wheel arch or a transmission tunnel were there is no clear upward escape for the fumes, the operator can only weld as the fumes disperse or try and distance yourself from the welding area. This is difficult as the operator needs to see the weld. Use a repirator (FIG 6) or a fan if the fumes are not clearing away from the operator by draft. Do not breath the fumes from galvanized steel, paint, underseal etc..
