11.   Do not touch the electrode while in contact with 

the work (ground) circuit.

12.  Use only well-maintained equipment. Repair or 

replace damaged parts as soon as practical.

13.  In confined spaces or damp locations, do not 

use a welder with AC output unless equipped 
with a voltage reducer.

Arc rays from the welding process produce intense 
heat and strong ultraviolet rays that can burn eyes 
and skin. Use the following table to select the appro-
priate shade number for a Welding Helmet or Weld-
ing Face Shield.

1.   Use a Welding Helmet or Welding Face Shield fit-

ted with a proper shade of filter (see AS 60974-1, 
AS/NZS 1337.1 and AS/NZS 1338.1 Safety Stand-
ards) to protect your face and eyes when weld-
ing or watching.

2.   Wear  approved  safety  glasses.  Side  shields  are 

recommended.

3.   Use  protective  screens  or  barriers  to  protect 

others from flash and glare; warn others not to 
watch the arc.

4.   Wear protective clothing made from durable, 

flame-resistant  material  (wool  and  leather)  and 
foot protection.

5.   Never wear contact lenses while welding.

Fumes And Gases

WARNING!

Welding produces fumes and gases. Breathing
these fumes and gases can be hazardous to your
health.

1.   Keep your head out of the fumes. Do not breathe
 

the fumes.

2.   If inside, ventilate the area and/or use an exhaust
 

at the arc to remove welding fumes and gases.
