renowned as one of the best in the industry. You should find this machine to be a solid
reliable machine capable of many years service.
Safety
Before using make sure all operators are familiar with the welding process and have had
appropriate training relating to all the risks involved.
Risk of burns & eye damage.
Risk from inhalation of welding fumes.
Risk of bodily crush damage in wire drive system.
The Health and Safety Executive publish documents regarding this such as ISBN 0 7176
0704 6 (Electrical safety in arc welding), and many others.
When welding or cutting in an environment with increased risk of electric shock extra
precautions must be observed. Typical conditions with increased risk of electric shock are
working in wet or damp conditions, working inside vessels, working in cramped conditions and
exposed to conductive parts, etc. DO NOT TAKE ANY RISKS
This machine is designed for use indoors and must not be used in the rain or a wet
environment.

- Page 4 250A. Too high a value would result in a hot unstable arc, too low a value would give rise to excess splatter and a cold poorly penetrating weld. The value of inductance on this Oxford machine has been selected to cover the entire welding range with excellent results.
- Page 5 The wire speed control and the wire size selected both affect the actual value of welding current achieved at a given welding voltage. Welding with this machine First ensure you are familiar with all risks & have taken necessary precautions. With the machine all set up ready to weld, the operator should first select an approximate voltage setting on the range switches, a little trial and error is needed when first selecting voltage settings, its generally better to start with a lowish voltage setting and increase if...

Page 6: Trouble Shooting Guide
Do not attempt any electrical repairs unless fully competent. Do not attempt any maintenance or inspection of the feed mechanism without switching machine to off or there is a risk of bodily crush damage in the wire feed. The welding torch & wire feed roller mechanism needs to be checked & cleaned regularly to ensure best performance;... - Page 7 Problem Machine welds but wire often burns back to the tip or sticks inside the tip. Solution Change the torch contact tip; make sure it is the same size as the wire being used. Check the torch liner is the correct size for the wire (see above) & in good condition, check the tension on the wire tensioner.
