Proventative Measures and Maintenance

Inverters should be used in dry environments, with humidity levels of 90% max.
The ambient room temperature should be between 10 to 40 ºC.
The Inverter should not be used in rain or drizzle or for long period in the sun.
Do not use the Inverter in corrosive areas.
The cooling fan fitted to the Inverter needs to keep the unit cooled to required limits, therefore, the intake air vents must not be obstructed, always clean and not within 0.3 meter to the nearest object. The WARRANTY of the Inverter allows for the operator to remove the cover to blow out excessive dust and metal dust particles using dry compressed air with reasonable pressure level, to prevent damage the electrical components. However, the WARRANTY will be nul and void if any component is changed or altered. Care should be taken that the cover is fitted back correctly as this can influence the correct air flow.
The duty cycle of the Inverter should not be exceeded. (See INFOWELD No. 6)
The input voltage should always be within the + - 15% under of over allowable voltage supply. Using input power cable exceeding 15 meters may cause the voltage to drop below this level and may damage the electronic components. (See INFOWELD No. 3. for cable information.)
When the overload protection device is activated (front indicator light will come on) the Inverter will switch off and the power will only be re-activated (front indicator light off) for further welding once the component temperature reaches safe levels. The cool down time may vary according to the conditions under which the Inverter is used. (See INFOWELD No. 6)
Prevent water or steam from entering the Inverter. Should this happen, remove the power supply from the mains and dry properly.
Inverters should not be used using power generators unless expensive voltage equalizers are fitted. The electronic components fitted to Inverters cannot absorb the excessive voltage variations found with this type of power supply.
