Accidental contact of electrode or welding wire to

metal  objects  can  cause  sparks,  overheating,  or

welding site.

4.  Be alert that welding sparks and hot materials 

from  welding  can  easily  go  through  small 

cracks and openings to adjacent areas.

5. 

nearby.

6. 

hidden side.

7.  Do  not  weld  on  closed  containers  such  as 

tanks or drums.

 

WARNING!

 

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.

Cylinders

1.  Protect  compressed  gas  cylinders  from 

excessive heat, mechanical shocks, and arcs.

2.  Install  and  secure  cylinders  in  an  upright 

position  by  chaining  them  to  a  stationary 

support or equipment cylinder rack to prevent 

falling or tipping.

3.  Keep  cylinders  away  from  any  welding  or 

other electrical circuits.

4.  Never allow a welding electrode to touch any 

cylinder.

5.  Use  appropriate  shielding  gas,  regulators, 

application;  maintain  them  and  their 

associated parts in good condition.

6.  Turn  your  face  away  from  the  valve  outlet 

when opening the cylinder valve.

3.  If  ventilation  is  poor,  use  an  approved  air-

supplied respirator.

4.  Read  the  Safety  Data  Sheets  (SDS)  and  the 

manufacturer’s  instruction  for  the  metals, 

consumables, coatings, and cleaners.

5. 

ventilated,  or  while  wearing  an  air-supplied 

respirator.  Shielding  gases  used  for  welding 

can  displace  air  causing  injury  or  death.  Be 

sure the breathing air is safe.

6.  Do  not  weld  in  locations  near  degreasing, 

cleaning, or spraying operations. The heat and 

rays of the arc can react with vapours to form 

highly toxic and irritating gases.

7.  Do  not  weld  on  coated  metals,  such  as 

galvanized,  lead,  or  cadmium  plated  steel, 

unless  the  coating  is  removed  from  the 

weld  area,  the  area  is  well  ventilated,  and 

if  necessary,  while  wearing  an  air-  supplied 

respirator.  The  coatings  and  any  metals 

fumes if welded.

8.  Connect  the  work  lead/clamp  to  the  job 

as  close  to  the  welding  area  as  practical  to 

prevent welding current from traveling long, 

possibly unknown paths and causing electric 

9.  Do not use a welder to thaw frozen pipes.

10.  Remove  the  stick  electrode  from  the  holder 

when not in use.

Sparks & Hot Metal

 

WARNING!

 

 

 

1.  Wear an AS/NZS approved face shield or safety 

goggles. Side shields are recommended.

2.  Wear appropriate safety equipment to protect 

the skin and body.
