PREPARATION OF THE WORKING AREA

The working area must be sufficiently spacious, not humid, and well-ventilated 
as to avoid any fumes which develop from the welding process and from 
incidental material adhering to the pieces to be welded (oils, paints, tars...) 
which may cause danger to the operator.

Avoid welding tanks which may contain flammable residuals.

ADDITIONAL PRECAUTIONS FOR MMA WELDING

1. ALWAYS ensure that there is full free air circulating around the outer casing 

of the machine and that the louvres are unobstructed.

2. A welding arc can seriously damage your eyes. Both operator and 

spectators must ALWAYS use a proper welding face shield or helmet with 
suitable filter lenses. Proper gloves and working clothes should be worn at 
all times.

3. ALWAYS remove all flammable materials from the welding area.

4. NEVER remove any of the panels unless the machine is disconnected from 

the supply and never use the machine with any of the panels removed.

5. NEVER use or store in a damp environment. DO NOT EXPOSE TO RAIN.

6. NEVER attempt any electrical or mechanical repair unless your are a 

qualified technician. If you have a problem with the machine contact your 
local CLARKE dealer.

7. ALWAYS keep a fire extinguisher handy (Dry Powder, C02 or BCF, NOT 

Water).

8. NEVER continue to weld, if, at any time, you feel even the smallest electric 

shock. Stop welding IMMEDIATELY and DO NOT attempt to use the 
machine until the fault is diagnosed and corrected.

9. NEVER allow the earth cable or torch to become wrapped around the 

operator or any person in the vicinity.

WARNING: ELECTRIC SHOCK CAN BE FATAL. A PERSON QUALIFIED IN FIRST 
AID SHOULD ALWAYS BE PRESENT IN THE WORKING AREA. IF PERSON IS 
UNCONSCIOUS AND ELECTRIC SHOCK IS SUSPECTED, DO NOT TOUCH 
THE PERSON IF HE OR SHE IS IN CONTACT WITH THE WELDER OR CABLES. 
DISCONNECT THE WELDER FROM THE POWER SOURCE AND THEN USE FIRST 
AID. DRY WOOD, OR OTHER INSULATING MATERIAL CAN BE USED TO 
MOVE CABLES, IF NECESSARY, AWAY FROM THE PERSON.
