4. ASSEMBLY
4.1.
ASSEMBLING THE WHEELS: (Refer to fig.1) The wheels are more easily
assembled with the welder placed upside down on a smooth non-abrasive
surface. The welder should be turned over by two people as it is very heavy.
4.1.1.
Bolt the two castors (1) to the front end of the base (2) using the bolts
provided.
4.1.2.
Take the solid axle (3) and slide a wheel (4) over one end followed
by a washer (5). Insert a split pin (6) through the hole in one end of the
axle as shown below and bend it over.
4.1.3.
Take an axle retaining bracket (7) and insert it into the slots in the base (2).
4.1.4.
Hold the bracket in place and slide the axle assembly through both parts of
the bracket. Insert the second axle retaining bracket (7) through the base
and continue to slide the axle across so that it passes through the second
bracket and holds the wheel (4) up against the side of the base. Slide the second wheel (8) onto the free end of the axle followed by a
washer (9). Retain the entire axle assembly by passing a split pin (10) through the free end of the axle and bend it over to retain the whole axle
assembly.
4.1.5.
With the assistance of another person turn the welder the right way up onto its wheels.
4.2.
ASSEMBLING THE HANDLE: (Refer to fig.2)
4.2.1.
On the front of the welder there are two pairs of threaded inserts, one pair in the top left corner and one pair in the top right hand corner.
Attach the left hand handle mounting (1) to the front of the welder using two of the 25mm round headed bolts provided. DO NOT fully
4.2.2.
tighten yet.
4.2.3.
Slide the handle tube (2) into the socket in the mounting and push fully home.
4.2.4.
Slide the socket on the right hand handle mounting (3) over the free end
of the handle tube and rotate the mounting downwards
until it is resting on the front of the welder. Using two of the
25mm round headed bolts provided to fix the right hand mounting
in place.
4.2.5.
Now fully tighten all four fixing
4.3.
ASSEMBLING THE EARTH CLAMP (Refer to fig.3)
4.3.1.
Feed the eyelet on the end of the earth lead through the hole in the clamp arm as shown in fig.3A.
4.3.2.
Drop the eyelet over the terminal and firmly fix with the bolt provided as shown in fig.3B.
4.4.
INSTALLING THE GAS CYLINDER
4.4.1.
The welder is designed to accommodate small or medium sized gas cylinders up to a maximum height of 1000mm. Contact your local Gas
dealer for supply.
4.4.2.
Place the gas cylinder onto the rear platform of the welder. Drop one end of the fixing chain into one side of the retaining bracket. 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
4.5.1.
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.
4.6.
CO² GAS
WARNING! 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 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.
4.7.
ARGON GAS OR ARGON MIXTURES
4.7.1.
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.
4.7.2.
Slide a jubilee 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. Tighten the clips to ensure a good seal.
4.7.3.
Close the regulator valve by turning it anticlockwise before opening the cylinder valve. Stand to one side when opening the cylinder valve.
4.7.4.
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.
4.8.
CONNECT THE TORCH CABLE TO THE WELDER
4.8.1.
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.
