OPERATING INSTRUCTIONS….cont
There are no hard and fast rules by which a particular gauge of electrode is selected,
usually this is determined by the type of welding required and the thickness of the
workpiece e.g. a butt weld in 1.5mm (1/16”) sheet metal can be done by a 1.6mm or
2.0mm electrode, the difference being that the 2.0mm electrode will do the job
more quickly.
The table below gives a guide as to which electrode is most suitable according to the
material thickness. This table is only a guide, and values given are an indication only.
These welding current values are for the E6013 electrodes, for other types of electrode
consult their data sheet.
Electrode Size mm Material Thickness mm Welding Current (A)
1.6
1 - 1.6
25 - 40
2.0
1.6 - 2.6
40 - 70
2.5
2.6 - 4.0
60 - 100
3.25
3.0 - 5.0
80 - 130
4.0
5.0 - 7.0
130 - 170
Note:
The above is a guide only; always try a short weld test at the setting
selected. It is normal to make minor adjustments to achieve the required
weld.
The welder should be set to a specific amperage to match the electrode size (see
table).
The amperage is set as part of setting the welding parameters as explained on page
16, 17 & 18.
AMPERAGE CONTROL
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.

ELECTRICAL CONNECTION
WARNING!
It is the responsibility of the owner and the operator to read, understand
and comply with the following:
You must check all electrical products, before use, to ensure that they are safe.
You must inspect power cables, plugs, sockets and any other connectors for wear or
damage.
You must ensure that the risk of electric shock is minimised by the installation of appro-
priate safety devices; A residual current circuit Breaker (RCCB) should be incorporated
in the main distribution board. We also recommend that a residual current device
(RCD) is used. It is particularly important to use an RCD with portable products that are
plugged into a supply which is not protected by an RCCB. If in any doubt consult a
qualified electrician.
Connecting to the power supply:
This Weldmate HG welder is supplied without a plug fitted, it must not be connected
to a 13A supply, consult the technical specification table (page13) for the required
rating, if in doubt contact a qualified electrician. Before using the welder, inspect all
the leads and plugs to ensure that non are damaged. If any damage is visible have
the welder inspected / repaired by a suitably qualified person.
The wires for the plug are coloured in the following way:
Yellow / green
Earth
Blue
Neutral
Brown
Live
As the colours of the wires may not correspond with the markings in your plug, pro-
ceed as follows:
The wire which is coloured brown, must be connected to the terminal, which is
marked L or coloured red.
The wire which is coloured blue, must be connected to the terminal marked with N or
coloured black.
The wire which is coloured yellow / green should be connected to the terminal which
is coloured the same or marked with this symbol
Always secure the wires in the plug terminal carefully and tightly. Secure the cable in
the cord grip carefully.
