PREFACE 1.1 General Congratulations on choosing the Minarc equipment. Used correctly, Kemppi products can significantly increase the productivity of your welding, and provide years of economical service. This operating manual contains important information on the use, maintenance and safety of your Kemppi product. The technical specifications of the equipment can be found at the end of the manual. Please read the manual carefully before using the equipment for the first time.
Minarc 150, 151 / © Kemppi Oy / 1117 1.2 Product introduction Kemppi Minarc is a manual metal arc welding machine, small in size, suitable for industry, site and repair welding. The unit uses one phase connection voltage and it is manufactured for two different mains voltages: 230 V (Minarc 150) and 110 V (Minarc 151). Minarc tolerates a great fluctuation of input voltage and is thus suitable for work on sites using generator as well as to be used with long power cables.
Serial number 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 Main components Connect welding cable and earth cable to their connections on the power source. Mains cable and wall plug are already installed. (Note! Minarc 151 (110 V) is delivered without a plug). Parts of the unit 1. 2. 3. 4. 5. 6. 7. 8.
Minarc 150, 151 / © Kemppi Oy / 1117 2.5 Distribution network All regular electrical devices without special circuits generate harmonic currents into distribution network. High rates of harmonic current may cause losses and disturbance to some equipment. Minarc 150, 150 VDR, 120 AU, 150 AU WARNING: This equipment does not comply with IEC 61000-3-12.
Use NOTE! It is forbidden to weld in places where there is a danger of fire or explosion! 3.1 Welding processes 3.1.1 Manual Metal Arc welding (MMA) In manual metal arc (MMA) the welding filler material is melted from the electrode to the weld pool. Rate of welding current is selected on the basis of electrode size used and welding position. Arc forms between electrode tip and welding piece. The melting electrode coating forms gas and slag, which protects the weld pool.

/ TIG Regulating welding current Welding current rate is regulated steplessly with an adjusting potentiometer. Signal light for overheating A yellow signal light of overheating is lit, when thermostat has tripped due to the unit’s overheating. Fan will cool the unit and after the signal light goes off, the unit is again ready for welding. 3.
Minarc 150, 151 / © Kemppi Oy / 1117 3.4 Welding selections NOTE! Welding fumes may be dangerous to your health, see that there is ample ventilation during welding! Never look at the arc without face shield made for arc welding! Protect yourself and your surroundings from the arc and hot spatter! 3.4.1 Earthing If possible, always fix earth cable clamp directly on the welding piece. 1. Clean connection surface of earth clamp from paint and rust. 2.
Maintenance NOTE! Be careful when handling electrical cables! In maintaining the unit, take into consideration the rate of use and the environment it is used in. When the unit is used properly and serviced regularly, you will avoid unnecessary disturbances in use and production. 4.1 Daily maintenance Perform the following maintenance daily: • Clean electrode holder and TIG torch’s gas nozzle. Replace damaged or worn parts. • Check TIG torch’s electrode. Replace or sharpen, if necessary.
