4.3.
ASSEMBLING THE EARTH CLAMP: (Refer to fig.3) Feed the eyelet on the end of the earth lead through the hole in the clamp arm as shown in
fig.3A.
4.3.1.
Drop the eyelet over the terminal and firmly fix with the bolt provided as shown in fig.3B.
4.4.
INSTALLING THE GAS CYLINDER. The welder is designed to accommodate small or
medium sized gas cylinders up to a maximum height of 1000mm.
Contact your local Gas stockist for supply.
4.4.1.
Place the gas cylinder onto the rear platform of the welder. See fig.2-P.
4.4.2.
Place one end of the fixing chain into one side of the retaining bracket.
4.4.3.
Draw the chain around the cylinder and place it into the slot on the other side of the
bracket leaving as little slack in the chain as possible.
4.5.
ATTACHING THE REGULATOR. Whichever gas you are using it is advisable to 'crack' the cylinder valve before attaching the regulator.
This means opening and closing the valve very quickly in order to blow away any dust and dirt that may have accumulated in the gas
outlet. Stand to one side whilst doing this.
CO² GAS. Ensure that the threads on the gas bottle are undamaged and free of oil and grease before attaching the regulator. (Oil or grease
4.5.1.
in the presence of high pressure gases can be explosive). Ensure that the regulator has an undamaged gasket fitted. The regulator will
screw directly to the threads on the gas bottle. Tighten with a spanner.
4.5.2.
ARGON GAS OR ARGON MIXTURES. Cylinders containing Argon gas and Argon mixtures have a female thread and will require the use
of a Bull Nose Adaptor to attach the regulator to the cylinder as indicated in fig.4. Ensure that the threads on the gas bottle are undamaged and
free of oil and grease before attaching the regulator. (Oil or grease in the presence of high pressure gases is explosive). Fit the Bull Nose
Adaptor to the cylinder first and tighten with a spanner. Ensure that the regulator has an undamaged gasket before fitting onto the Bull
Nose Adaptor. Tighten with a spanner.
4.5.3.
Slide a clip over each end of the gas hose supplied. Push one end of the hose onto the regulator outlet and the other end over the gas
inlet spigot on the back of the welder. See fig.2G. Tighten the clips to ensure a good seal.
4.5.4.
Close the regulator valve by turning it anticlockwise before opening the cylinder valve. Stand to one side when opening the cylinder valve.
4.5.5.
Set the regulator flow rate to 5-8 litres/min depending on the material to be welded, and whether there are draughts which are strong
enough to disturb the gas flow.
4.6.
CONNECT THE TORCH CABLE TO THE WELDER.
Align the pins on the Euro connector with the socket on the
welder front panel as shown in fig.5. Push the connector into
the socket and rotate the locking ring (A) clockwise so that it
draws the plug into the socket as shown in fig.6.
NOTE: damage to torches and cables is not covered by warranty.
4.7.
FITTING A 15KG REEL OF WIRE.
Ensure that the wire diameter used, is matched by the correct
groove size in the drive wheel and the correct tip size on the
torch as well as the correct torch liner. Failure to do this could
cause the wire to slip and/or bind.
4.7.1.
Unscrew the locking knob from the end of the spool holder
(see fig.7C) and remove the spacer (B). The spacer is not required for 15kg reels of wire. Slide the reel of wire onto the spool holder and
ensure that the clutch pin at the back of the spool holder (E) engages into the guide hole in the wire reel moulding. This will prevent the
wire reel from freewheeling on the spool holder. Ensure that the wire is coming off the bottom of the reel in the direction of the wire drive
unit as shown in fig.8.
