SECTION 1:
SAFETY INSTRUCTIONS AND WARNINGS
WARNING
seRious injuRy oR death May Result if Welding and cutting equipMent is not pRopeRly installed,
used and Maintained. Misuse of this equipMent and otheR unsafe pRactices can be hazaRdous. the
opeRatoR, supeRvisoR, and helpeR Must Read and undeRstand the folloWing safety WaRnings and
instRuctions befoRe installing oR using any Welding oR cutting equipMent.
the Welding and cutting pRocess is used in Many potentially dangeRous enviRonMents such
as elevated heights, aReas of liMited ventilation, close quaRteRs, aRound WateR, in hostile
enviRonMents, etc., and it is iMpoRtant that the opeRatoR(s) aRe aWaRe of the dangeRs associated
With WoRking in these types of conditions. be ceRtain that the opeRatoR(s) aRe tRained in
safe pRactices foR enviRonMents in Which they aRe expected to WoRk and undeR coMpetent
supeRvision.
it is essential that the opeRatoR, supeRvisoR and all otheR peRsonnel in the WoRk aRea aRe aWaRe
of the dangeRs of the Welding oR cutting pRocess. tRaining and pRopeR supeRvision aRe iMpoRtant
foR a safe WoRk place. keep these instRuctions foR futuRe use. additional RecoMMended safety
and opeRating infoRMation is RefeRenced in each section.
5. All ground connections must be checked periodically
to determine that they are mechanically strong and
electrically adequate for the required current.
6. When engaged in alternating current, welding, or
cutting under wet conditions or warm surroundings
where perspiration is a factor, the use of reliable
automatic controls for reducing the no-load voltage
is recommended to reduce shock hazard.
7. When the welding or cutting process requires values of
open circuit voltages in alternating current machines
higher than 80 volts, and direct current machines
higher than 100 volts, means must be provided to
prevent the operator from making accidental contact
with the high voltage by adequate insulation or other
means.
8. When welding is to be suspended for any substantial
length of time, such as during lunch or overnight,
all electrodes should be removed from the electrode
holder and the electrode holder carefully located so
that accidental contact cannot occur.
9. The holder must be disconnected from the power
source when not in use.
10. Never immerse Mig-Guns, electrode holders, tig
torches, plasma torches, or electrodes in water.
WARNING
sMoke, fuMes, and gases can be dangeRous
to youR health.

1. Do not touch live electrical parts.
2. Do not touch an electrode with bare skin and electrical
ground at the same time.
3. Always keep welding gloves dry and in good
condition.
NOTE
aluminized protective clothing can become
part of the electrical path.
4. Keep oxygen cylinders, chains, wire ropes, cranes,
hoists, and elevators away from any part of the
electrical path.
