Maintenance - HBM Machines ARC 200 Handbuch

1) The working area is adequately ventilated!
The welding machine is powerful machine.When it is being operated, it generated by high current, under
this situation,natural wind will not satisfy machine cool demands. So a fan is used into inner-machine to cool
down itself. Make sure the intake is not blocked or covered.The objects around the welding machine should
be kept away not less than 0.3 meters.Make sure the working area adequately ventilated is specially
necessary. It is vitally important for the performance and longevity of the machine.
2) No over load!
The operator should remember to watch the max duty current (Response to the selected duty cycle). Keep
welding current is not exceed max duty cycle current. Over-load current will damage and burn up machine.
3) No over voltage!
Power voltage can be found in diagram of main technical data. Automatic compensation circuit of voltage
will assure the welding current keep in allowable range. If power voltage exceeds the allowable range limited,
it will damage to components of machine. The operator should understand this situation and take preventive
measures.
4) There is a grounding screw behind welding machine, with a grounding marker on it. Before operation,
welding crust must be grounded reliable with cable which section is over 6 square millimeter, in order to
prevent from static electricity, and accidents possibly caused by electricity leaking.
5) If welding time exceeds the duty cycle limited, welding machine will stop working for protection. Because
machine is overheated, temperature control switch is on "ON'' position and the indicator light is yellow (red). In
this situation, you needn't pull the plug, in order to let the fan cool the machine. When the indicator light is off,
and the temperature goes down to the standard range, it can weld again.

8. MAINTENANCE:

1. Remove dust by dry and clean compressed air regularly, if welding machine is operating in environment
where is polluted with smokes and pollution air, the machine need remove dust every month.
2. Pressure of compressed air must be within the reasonable range in order to prevent damaging to small
components of inner-machine.
3. Check internal circuit of welding machine regularly and make sure the circuit connections are connected
correctly and tightly (especially plug-in connector and components). If scale and rust are found, please clean
it, and connect again tightly.
4. Prevent water and steam from entering into the machine. If that happens, please blow it dry and check
insulation of machine.
5. If welding machine will not be used for long time, it must be put into the packing box and stored in dry and
clean environment.
