3. ARC WELDING
Slag
Slag is refuse left around the weld
after welding, this should only be
removed after the weld has cooled
down and is no longer glowing.
Face shield must be worn during
removal of slag.
Welding Current Control
The welding current can be increased or decreased by turning the
welding current control knob. The welding current should be set
according to the specific application and material.
OPERATION
Preparation
Before welding ensure that:
•
You have read and understand the safety section of this manual.
•
There is sufficient ventilation, particularly at the front and rear of
the unit.
•
You have an adequate fire-fighting devices on hand.
Electrodes & Welding Current
The welding current must be regulated in accordance with the diameter
of the electrode and the thickness of the steel being used.
This will vary with the type of electrodes and material you are using.
Below is a guide suggesting suitable currents & thickness for welding
steel.

Striking the Arc
Lower the electrode slowly and proceed to strike the electrode tip
against the desired join area on the work piece as if you are striking
a match. As soon as you have the arc, try to maintain a distance from
the work piece equal to the diameter of the electrode being used, eg
2.0mm electrode, 2.0mm gap.
WARNING:
ENSURE ALL OIL, PETROL AND FLAMMABLE
CONTAINERS HAVE BEEN REMOVED FROM WELDING
AREA.
WARNING:
ENSURE APPROVED PROTECTIVE
CLOTHING AND WELDING HELMET/MASK IS WORN AT
ALL TIMES TO PROTECT YOUR FACE AND EYES FROM
ARC UV RADIATION AND SPARKS.
1 To increase the welding
current turn the current control
knob in a clockwise direction.
2 To decrease the welding
current turn the current control
knob in a anti-clockwise
direction.

Thermal Overload LED
The Power ON Indicator
illuminates when the power cord
is connected to a live mains
outlet.
When illuminated, wait for
the LED to extinguish before
resuming welding.
Note:
The cooling fan will operate
when on.
Note:
This can occur in heavy use
and does not indicate a fault.
