Maintenance & Troubleshooting
1 - The dust that is accumulated inside the welding machine should be cleaned by pressured air
regularly. If the machine is used in an environment which contains too much dust and fume,this
procedure should be performed twice a month.
2 - To protect small parts, be careful about the air pressure while cleaning.
3 - Welding cable connections should be checked frequently and make sure that the connections
are proper. Loose connections should be replaced. When socket surfaces are oxidized or
break down, these surfaces should be cleaned or replaced with the new one.
4 - Avoid water or vapour getting inside the welding machine. If the machine is effected by
humidity, it should be dried up and its isolation should be checked.
5 - If the welding machine won't be used for extended periods, it should be placed inside the
plastic package and kept in a dry environment.
6 - When lifting, the welding machine shouldn't be thrown randomly and be protected from blows.
