Plasma cutters are effective tools for heavy-duty jobs, but like any piece of heavy machinery, they can run into a variety of mechanical problems. If you’re experiencing problems with your plasma cutter and can’t find the cause, we’re here to help. This guide will take you through the most common plasma cutter issues so you can keep both your machine and your welds in great shape.
Many common issues with plasma cutters stem from not treating the torch the right way. Excessively knocking the torch against the workpiece will cause damage to it that can result in certain components failing over time. If you take good care of your torch, it can last you a while. But if you’re constantly hitting the torch against the workpiece or other objects in the environment, it won’t be able to help you complete projects for very long. If the problem with your torch seems to be improper handling, then it might be time for a replacement.
When preparing your plasma cutter for the weld, don’t treat the air pressure levels like they’re optional—they’re far from it. If you supply your plasma cutter with too much air pressure, you’re going to wear out your consumables at an excessive rate. That being said, if you turn the air pressure down too low, then you’re not going to be able to produce a sufficient plasma arc. Not every plasma cutter is made the same, so consult the manufacturer’s recommendations regarding air pressure so you can find the right levels for your specific machine.
If you want a clean weld, then you’re going to need a clean torch. Thus, you should regularly inspect your torch for buildup of any kind. After each use, carefully wipe your torch components with a shop towel or metal brush. If your torch gets too dirty, it will contaminate the weld and ultimately lead to a low-quality final result. Additionally, keep your torch stored in a secure area to ensure you don’t contaminate it between welds.
Thanks to this guide to three of the most common plasma cutter issues, you’re ready to obtain and maintain high-quality plasma cutter machines. Running into technical difficulties with your plasma cutter and failing to find a cause or a solution can be frustrating. If you inform yourself on the ins and outs of plasma cutter care, these powerful machines will assist you in completing efficient, high-quality welds for quite some time.
