4. AIR SUPPLY
An air supply is required to operate the pneumatic clamps. See fig. 1 for the recommended hook-up.
4.1.
Ensure that the air valve is in the "off" position before connecting to the air supply.
4.2.
The pneumatic clamps require a compressed air supply of 6 to 8 bar connected to the filter-regulator at the rear of the welder.
4.3.
! WARNING! Ensure that the air supply does not exceed 8 bar while operating the welder. Too high an air pressure and/or
unclean air will shorten the product life, due to excessive wear, and may be dangerous,
causing possible damage and/or personal injury.
4.4.
Drain the air tank daily. Water in the air line will damage the clamp.
4.5.
Clean the compressor air inlet filter screen weekly.
4.6.
Line pressure should be increased to compensate for
unusually long air hoses (over 8 metres). The minimum
hose diameter should be 10mm I.D. and fittings must
have the same inside dimensions.
4.7.
Keep hoses away from heat, oil and sharp edges.
Check hoses for wear, and make certain that
all connections are secure.
5. TROLLEY ASSEMBLY
A diagram showing the assembly of the trolley may be found at the end of these Instructions.
! WARNING! DO NOT attempt to put the spot welder onto the trolley until you are certain that all the trolley assembly fixings are tight and
that the wheels have been correctly mounted.
