Kemppi Minarc EVO 180 Machine Parts FAQs
Frames, covers, cables, connectors and carrying parts for a compact stick welder, and how to match and fit them safely.
How do I identify the right spare for my machine?
Start with the rating plate on the machine. It shows the maker's type designation and serial number, and it is the usual place to find the supply, performance and standards information for that machine. Quote the type and serial number together with the position or appearance of the part and its number in the manual's parts list.
The same family often includes close variants with different covers, cables or plugs, so a part that looks the same may not fit. Compare the old part with the new one before fitting, and keep the plate details with your records. Our team can help you match the part to the machine.
Can I replace the mains cable myself?
Treat a mains cable or plug replacement as a job for a competent person, such as a qualified electrician, and check your manual, which will normally say who may do it. A damaged cable should be replaced rather than patched, by a competent person, and insulating tape or an unsuitable connector is a sign of a fault, not an acceptable repair.
The replacement must match the maker's specification for cable type and conductor size, and be properly clamped where it enters the machine. Do not use the machine until the work has been done and checked.
How do I know if a cable, connector or output socket is damaged?
Look before each use, with the machine unplugged. The welder should check the cable, electrode holder and couplings regularly for damage, report any defects, and keep external connections clean and tight, including after every reconnection. Your manual will list the checks for your machine.
Replace a cable with cuts, exposed conductors, crushed or melted insulation, or a plug that is loose, cracked or discoloured. A connector or socket that runs hot, looks pitted or discoloured, or does not seat firmly may have a poor connection, which can cause overheating and arcing. Do not drag the machine by its cables, and leave repairs to a socket on the machine to an authorised person.
How often should I clean the dust out of the machine, and how?
Follow your own manual, because makers differ on both the interval and the method. Some say to clean the interior and fan grille at regular intervals with a soft brush and vacuum cleaner rather than pressurised air, because dirt can be packed into the cooling fins. Others allow dry, low-pressure compressed air used with care and never blown onto the fan.
Unplug first and wait before removing the case, as capacitors can hold a charge. The wait differs between makers, so use the time stated in your manual. Wear eye protection and a dust mask, and clean more often in dusty workshops.
