Power Output switch. Set the switch to position 1 or 2 for welding up to 2mm thickness. Use settings 3,4,5,6. for thicker welds.
5.2.2.
Setting the welder controls. In principle, the lower the amperage required, the slower the wire speed. See setting chart below for
voltage and corresponding wire speeds. Note: these settings are only a guide and will vary according to the operator's experience.
5.2.3.
Welding mild steel. To weld mild steel you can use CO ² gas for most tasks where spatter and the high build up of weld do not pose a
problem. Welding with a long arc reduces penetration and widens the arc. This in turn results in more spatter. A long welding arc can be
appropriate for welding butt joints in thin materials. Welding with a short arc, at the same weld settings, results in greater penetration
and a narrower weld and reduces the amount of spatter. To achieve a consistent spatter free and flat weld, you must use an Argon/CO
mixture.
5.2.4.
To weld aluminium use:
Argon gas,
0.8mm Contact Tip,
0.8mm Aluminium Wire,
5.2.5.
Overload Protection. Thermostatic overload protection is provided. When an overload has occurred, leave the unit to cool. The
thermostat will automatically reset the unit when the temperature has returned within limits
Spot Welding. Spot welding may be carried out as shown in fig.16. It will be necessary to fit a spot welding gas cup.
5.2.6.
(a) Overlapping metal sheets with a maximum thickness of 0.8 mm may be welded as indicated.
(b) Alternatively they may be welded edge to surface as indicated.
(c) For thicker sheet pre drilled holes holes may be employed.
Use the wire feed control in conjunction with the spot weld timer beside it. To activate the timer turn the knob clockwise. The settings
indicated in the spot welding section of the chart are for guidance only and may vary with operators experience.

RATINGS PLATE (SEE ABOVE)
r
On the front of the welder is the ratings plate, giving the following data:
1 - The standard relating to the safety and construction of arc welding and associated equipment.
2 - Single phase transformer - rectifier.
3 - Welding with a continuous flow of welding wire.
4 - Single-phase AC supply.
5 - Rating of internal protection provided by casing.
6 - Output
U0: Rated minimum & maximum no load voltage.
I2, U2: Current and corresponding voltage.
X: Welding ratio based on a 10 minute cycle. 20% indicates 2 minutes welding and 8 minutes rest, 100% indicates continuous welding.
7 - Mains Supply
U1: Rated supply voltage and frequency.
8 - Welding current range.
9 - Serial Number. Specifically identifies each welder.
