The specications and designs presented in this manual are subject to change without prior notice. In this document, the following symbol is used the symbol is used to indicate a risk of injury or
death:
Read the warnings carefully and follow the instructions. Please also study the instructions for safe operation and follow them when installing, operating and servicing the machine.
1.2. PRODUCT INTRODUCTION
The Kempact MIG 2520 is compact MIG inverter suitable for repair and installation use, and for
light and medium industrial use. The power source and the wire feeding mechanism are contained in the device. The power regulation of the power source is implemented with IGBT transistors operating at a frequency of approximately 30 kHz.
1.3. SAFE OPERATION
Read the warnings carefully and follow the instructions.
Welding arc and spatter
The arc and the reected radiation from it can damage unprotected eyes. Shield your eyes and protect your surroundings appropriately before you start welding. The arc and welding spatter will burn unprotected skin. When welding, use protective clothes and clothing.
Danger of re and explosion
Observe the re safety instructions. Remove ammable material in and near the location in which you will weld. Have the necessary re extinguishing equipment at hand. Note the dangers posed by special jobs, such as the risk of re and explosion when welding tanks. Note! Sparks may ignite a re even hours later! Welding is working with re, note the special instructions for such work.
Mains voltage
Never bring the welding machine inside the work piece (e.g. container or car). Never set the welding machine on a wet surface. Replace faulty cables immediately, they create a danger to life and can cause a re. See that the connecting cable does not stick, touch sharp edges, or come in contact with a hot piece.
Welding current circuit
Isolate yourself from the welding current circuit by wearing dry and undamaged protective clothing. Never work on a wet surface. Never use damaged welding cables. Never set the electrode holder, earth clamp, or welding cables on top of the power source or other electrical equipment.
Welding fumes
Ensure adequate ventilation. Always take special measures when welding metals containing lead, cadmium, zinc, mercury, or beryllium.
This equipment’s electromagnetic compatibility (EMC) is designed for use in an industrial environment. Class A equipment is not intended for use in residential location where the electrical power is provided by the public low-voltage supply system.

2. BEFORE YOU START USING THE UNIT
2.1. UNPACkING
The equipment is packed in durable packages, designed specially for it. Nevertheless, before using the equipment, always make sure it was not damaged during transport. Also check that you have received what you ordered and that there are instructions for it. NOTE! The packaging material of
the products is suitable for recycling.
2.2. PLACEMENT OF THE UNIT
Place the unit on a horizontal, solid, and clean surface. Shield it from heavy rain and scorching sun. Make sure that cooling air circulates freely.
2.3. SERIAL NUMBER
The serial number of the unit is marked on the rating plate of the unit. The serial number makes it possible to trace product manufacturing series. You might need the serial number when placing spare parts orders or when planning maintenance.
2.4. CONNECTION TO THE MAINS SUPPLY
The Kempact 2520 is delivered equipped with a ve metre mains cable without a plug. Installation of the plug should be carried out only by a competent electrician. For fuse and cable sizes, see the
technical data in the end of this document.
2.5. GROUND CABLE
Fasten the earth clamp of the return current cable carefully, preferably direct onto the piece to be
welded. The contact surface of the earth clamp should always be as large as possible. Clean the
fastening surface from paint and rust. Use at least 35 mm² cables. Thinner cross-sectional areas cause overheating of connectors.
2.6. WIRE FEEDING MECHANISM COMPONENTS
Wire feed motor
Clamp screw
Clamping lever
Wire guide
Feed roll and screw
Gun connector (Euro)
