OPERATION
WORKING ENVIRONMENT
This equipment is designed for use in the following conditions:
•
Areas free from moisture and dust with an ambient temperature between 0° to 40°C
•
Areas free from oil steam and corrosive gases
•
Areas usually not subjected to abnormal vibration or shock
•
Areas with suitable ventilation free from any flammable or combustible materials
•
Areas not exposed to direct sunlight or rain
Ensure that the equipment is not placed at a distance of 12” (304.79mm) or more from walls or similar obstructions that could restrict the natural
airflow or cooling of the system.
CONNECTING TO THE POWER SUPPLY
Warning:
Jefferson Tools recommends that this equipment be grounded and connected by a qualified electrician before use.
Connect the earth
cable to a suitable ground in compliance with the applicable electrical regulations. Connection to the correct input supply is necessary to avoid
damage to internal components.
Connect the power cable to the required voltage. The primary cable should be connected to the correct supply to avoid arcing or overheating.
Ensure that the input power supply is rated to match the maximum output of this equipment (AC, Single Phase, 50Hz, 230V).
WELDING CURRENT & ARC VOLTAGE
The welding power source is designed with a coiled safety feature that can withstand short-term overload without any adverse effects.
The welding current range values indicated on the control panel and specification plate should be used as a guide only. The current delivered to
the arc is dependent on the welding arc voltage and because the welding arc voltage can vary between different classes of electrodes, the
welding current at any one setting would vary depending on the type of electrode in use.
Use the supplied welding current range values as a guide and then adjust the current setting to suit the welding materials and processes you
are using.
CABLE & ELECTRODE CONNECTION
Before connecting the work clamp to the work piece and inserting the electrode in the electrode holder make sure the primary power supply to the
welder is disconnected.
