serious accidents. Do not
pile gas cylinders up and never expose
them to excessive heat, flames or
sparks. Do not bang cylinders against
each other. Contact your supplier for
more information regarding the use and
maintenance of gas cylinders.
WARNING:
Never use cylinders that are
damaged or show signs of oil or grease
leakage. Contact your supplier
immediately of any such circumstances.
8. WELDING METHODS
8.1 Manual MIG welding
To select this mode, turn knob 5 (Fig.1)
to the MIG MAN setting.
N.B.:
These are guidelines only and are
to be considered applicable solely to
workpieces no thicker than 4mm.
The settings are selected according to
wire diameter, location and welding gas.
Proceed as follows for manual MIG welding:
1.
Set the welding current, according to
the thickness of the workpiece and the
diameter of the wire to be used, using
the knob 8, Figure 1 (Step 1, Fig8). The
display panel (Fig. 1 – 1) shows the
value selected.
2.
According to the diameter of the wire,
set the wire speed using knob 7 of
Figure 1. (Step 3, Fig.8)
Step 1:
Current selection
Convert the thickness of the
workpiece in to Amperes (A)
using the following formula:
0.025mm = 1A
i.e. 3mm = 125A
Step 2:
Wire diameter selection
