OPERATION
Plug the machine into the mains supply or switch on at the isolator and ensuring
all precautions have been taken and with the machine set up correctly, lower
the torch to the workpiece with one hand, whilst holding the welding mask in the
other.
Approach the work with the tip at an angle of approx. 45
O
and pull the torch
trigger fully.
As the electrode touches the workpiece, an arc will be struck......before it is struck,
cover the face with the face mask.
Simultaneously gas will be generated, if the wire is flux cored, or gas will be issued
if you are gas welding, and the wire will be fed into the molten pool.
Maintain a gap of approx. 5 - 7mm from the workpiece to the tip.
The speed of weld will depend upon the wire speed and welding current. It is
advisable to test your settings on a scrap piece of metal with similar characteristics
to those of the workpiece. Fine tune the welding speed and/or current flow, as
required, until a satisfactory weld is achieved.
Listen to the sound made. An irregular crackling sound denotes too high a wire
speed. Decrease the speed until a regular, strong buzzing sound is heard.
Whenever the welding current regulation is changed, a corresponding change
in wire speed may be necessary. If the speed is too slow, the wire will weld itself to
the tip.
WELDING TIPS
1.
Try to maintain the tip of the nozzle at an angle of approx. 45
O
and at a constant
distance of approx 5-7mm from the workpiece.
2.
Try to maintain a constant speed of movement with the torch.
3.
Do not weld in windy conditions or in an area where ventilation is a problem,
or where air flow fluctuates.
4.
ALWAYS keep the wire and nozzle clean...NEVER use rusted wire.
5.
Avoid sharp bends or kinks in the welding hose.
6.
Whenever possible, clean out the wire liner with compressed air when
replacing the wire spool.
7.
Periodically remove the dust, using LOW PRESSURE compressed air, within the
casing. Adequate heat dissipation is essential during the welders operation.
