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 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.
4.5.4
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 REEL OF WIRE.
These units will accept either a 5kg or
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.7) and remove the spacer. Slide the reel of wire onto the spool
holder and ensure that the clutch pin at the back of the spool
holder engages into the guide hole in the wire reel moulding. This
will prevent the wire reel from freewheeling on the spool holder.
When using a 5kg reel, slide the spacer onto the spool holder
before refixing the locking knob. Ensure that the wire is coming off
the top of the reel in the direction of the wire drive unit as shown in
fig.8 which shows a 15kg reel of wire in place on the spool holder.
4.8
FEED WIRE THROUGH TO TORCH.
Open the wire feed
mechanism by pushing the locking/wire tension knob (1) down
to the right allowing the pressure roller carrier (2) to spring up
revealing the feed roller as shown in fig.9. Ensure that the required
feed groove (0.6 or 0.8) is in line with the wire path. See Section
3.12 on how to reverse or change the roller.
4.8.1
Release the wire from the reel and cut off any bent portion
ensuring that there are no burrs left on the end of the wire. Keep
the wire under tension at all times to prevent it uncoiling.
4.8.2
Straighten about 40-50mm of wire and gently push it through the
flexible metal sheathed cable (3) and through the 6 or 8mm feed
roller groove and on into the torch cable liner.
4.8.3
Push down the pressure roller carrier onto the wire feed roller and
hold it down. Lift up the locking/wire tension knob so that it enters
the slot in the pressure roller carrier and snaps into the indent in
its top surface. See fig.11. Rotate the tension knob to a medium
setting i.e. between 2 and 3.
4.8.4
Remove gas cup (fig.10-2) and contact tip (1) from end of torch as
follows: a) Take torch in left hand with the torch tip facing to the
right. b) Grasp gas cup firmly in your right hand. c) Turn gas cup
clockwise only and pull it off end of torch tip.
• WARNING! do not turn gas cup anti-clockwise, as this will
