2. Installation

Unpacking
Check the packaging for any signs of damage. Carefully remove the machine and retain the packaging until the
installation is complete.
Positioning of the machine
Place the machine on a firm, dry and level surface. Where possible, do not allow dust or other impurities to enter
the machines cooling air flow. Preferably site the machine above floor level; fsuch as a suitable carriage unit.
Notes for positioning the machine
• Make sure there is at least 20cm clearance at the front, rear and sides of the machine to allow good circulation
of the cooling air.
• Ensure that the machine is positioned in such a way that particles created by grinding and cutting operations
do not enter the machine.
NOTE! Damage caused by metal particles and water entering the machine will not be covered under warranty.
WARNING! All electric shocks are potentially fatal, a competent electrician should under-take the fitting of the
mains plug.
Connecting to mains supply
• Make sure that the mains supply is of the correct voltage and current
capability for the machine.
• Make sure that any extension cables used are of sufficient current
carrying capacity.
• Make sure that the mains plug and socket (if fitted) are in good
condition and are of the correct current carrying capacity. If the machine
is wired directly to the mains supply then an isolator switch must be
fitted.
NOTE! See technical specifications page for correct supply information
Primary cable length
Long extension cable lengths may reduce the performance of the machine, the welding arc may become
unstable especially at higher currents. Ensure the mains cable is not coiled up when you are welding as this will
reduce the input voltage to the machine and may cause overheating and degradation of the cable.
Setting supply voltage tapping
WARNING! All electric shocks are potentially fatal, a competent electrician should carry out any supply voltage
tapping adjustments required.
• To enable the setting of the supply voltage tapping, the front panel display cover of the R4000/R5000 has to be
removed.
• The photograph above shows the voltage tapping set to 415V, with the red wire from the fuse holder connect-
ed to the 415 terminal.
• This connector can be moved to the required voltage terminal to select the desired input voltage.
