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

annoyance to the operator.

Avoid welding by contact with humid parts nearby combustible liquids. Least of

all, do not weld upon tanks which may contain inflammable residuals.

SAFETY EQUIPMENT

A comprehensive range of CLARKE safety equipment for use when welding is

available from your local CLARKE dealer.

SAFETY PRECAUTIONS for ARC/TIG WELDING

ALWAYS 

ensure that there is full free air circulating around the outer casing of

the machine, and that the louvres are unobstructed.

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.

ALWAYS 

check that the pressure regulator and gauges are working correctly.

DO NOT lubricate the regulator.

ALWAYS 

use the correct regulator. Each regulator is designed to be used with

a specific gas.

ALWAYS 

inspect the hose before use to ensure it is in good condition.

ALWAYS 

 keep the free length of gas hose outside the work area.

ALWAYS 

remove all flammable materials from the welding area.

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.

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.
