Switching from one setting to another automatically increases and decreases the
wire speed and therefore the welding output. On material from 0.6mm up to 1 - 3
mm select "Low" setting(s) and for thicker materials select "High" setting(s).
NOTE: The wire feed speed is automatically adjusted when the output is selected.
The wire speed setting control provides fine-tuning.
USING THE WELDER
Before welding ensure that
a) Your MIG welder is earthed. Connection to a suitable fused isolator
switch, with the wires connected as follow:
b) BROWN= live, BLUE= neutral, GREEN/YELLOW= Earth
c) You have read and understood the safety section of this instruction
manual.
d) All flammable materials and containers have been removed from the
work area.
e) There is good ventilation, particularly at the front and rear of the welder.
f) There is an adequate fire-fighting appliance close by.
Then:
1. Connect the earth clamp onto the metal to be welded.
2. Set output and wire feed speed by turning or pressing the appropriate
controls (see Fig. A and B), taking into account the material type and
thickness and the wire size.
3. Plug in and switch the welder on.
4. Cut off excess wire to 3mm from the end of the tip.
5. Position the tip 6mm from the point where the welding is to start.
6. Hold the mask in front of your eyes.
7. Press the trigger and when the arc strikes, slowly move the torch in the
desired direction.
8. If the arc produces a humming sound and a blob forms on the end of the
wire, there is insufficient wire speed and it should be increased, (f an
erratic sound is given with a feel that the wire is stubbing against the
work and excessive spatter, there is too much wire speed. When the
speed is correct there will be a steady smooth crackling sound. If a
porous weld results there is insufficient gas flow and it should be
increased.
