Thank you for purchasing this British made Oxford welding machine. 
With a history dating back over 50 years Oxford welding machines are internationally 
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.
