Connecting to the power supply 05707:
The 05707 is supplied without a plug fitted, it must not be connected to a standard
13A supply, consult the technical specification table (page14) for the required rating,
if in doubt contact a qualified electrician.
ELECTRICAL CONNECTION….cont
Note:
If an extension lead is necessary in order to reach the mains supply; The
cross section should be checked so that it is of sufficient size so as to reduce the
chances of voltage drops. Always fully unwind the lead during use.
Warning:
Never connect live or neutral wires to the earth terminal of the plug.
Only fit an approved plug with the correct rated fuse. If in doubt consult a
qualified electrician.
Note:
Always make sure the mains supply is of the correct voltage and the
correct fuse protection is used. In the event of replacing the fuse always
replace the fuse with the same value as the original.
Note:
Due to the input current required to run the inverter welder, it is advisa-
ble not to use an extension lead. No more than 1 welder should be ran
from the same ring main for the same reason.

OPERATING INSTRUCTIONS….cont
Fit the required electrode securely into the electrode holder.
Switch the welder on.
Set the amperage control to match your electrode size.
Place a face mask over your face (not supplied).
Bring the electrode into contact with the workpiece using a light tapping action
and withdrawing to create a gap of 1.5 mm – 3.0 mm.
Note:
Be aware that the electrode is now live, simply touching any part of
the workpiece will create a spark.
When the arc is created, proceed steadily in one direction keeping the gap
between the electrode and the workpiece constant.
When the weld is complete simply remove the electrode from the workpiece.
Remove any excess weld / slag with a wire brush / hammer (not supplied).
Clean the area to be welded, and the earthing point of all rust, paint and con-
taminants etc.
Place the earth clamp on to a cleaned area of the workpiece.
Connect the welder to the electrical supply but do not switch on.
Caution:
Ensure all protective equipment is worn and bystanders are not in
the vicinity.
You will need to purchase the following items in order to TIG weld (not supplied):
TIG torch (with gas valve) - SIP Part No. 05029 Regulator
Tungsten electrode
Bottle of argon gas
Filler rod
PREPARATION FOR WELDING

TIG WELDING
The amperage control is operated by rotating the knob on the front of the welder;
Rotate the knob clockwise to increase the amperage and anticlockwise to reduce
the amperage. Once the amperage control is set do a short weld and check for cor-
