Suitable Welding Rod Diameter. Duty Cycle at 40? /104? Please make sure the heat dissipation holes are uncovered and unblocked. Good ventilation is of critical importance to the normal performance and service life of the machine. Please keep hands, hair, and tools away from the cooling fan to avoid personal injury or machine damage. The minimum distance between the machine and nearby objects should be 30cm/11inch. Clean the dust periodically with dry and clean compressed air. If welding in an environment with heavy smoke and pollution, the machine should be cleaned daily. The pressure of compressed air should be at a proper lever lest the small parts inside the machine will be damaged. Please avoid rain, water, or vapor infilter the machine. If there is, dry it and check the insulation with a megger (including that between the connections and that between the connection and the case). Only when there are no abnormal phenomena can welding be continued. Check periodically whether the inner circuit connection is ok esp. Tighten the loose connection. If there is oxidization, remove it with sandpaper and then reconnect. Check periodically whether the insulation skin of all cables is in a good station. If there is any dilapidation, wrap it or replace it. Put the machine into the toolbox in a dry location if it is not to be used for a long time. Please read the manual completely before installation and use, and pay particular attention to the safety instructions included. Feedback is very important to us.
