Introduction: The “Bigger is Better” Myth
If you are looking to buy your first fiber laser marking machine, or upgrading an old one, you are likely staring at the spec sheets and wondering:
“Do I really need 50 watts? Or is 20 watts enough?”
It is the most common question we get at HeatSign. There is a misconception that higher wattage equals “higher resolution.” That is not true. Wattage is about energy density and speed, not image clarity.
Think of it like a car engine. A Ferrari (high horsepower) and a Honda (lower horsepower) can both drive at 60 mph. But if you need to tow a heavy trailer up a hill (deep engraving), the Ferrari will get there much faster.
In this guide, we will cut through the marketing noise and give you a reality check on the Speed vs. Depth trade-off, and the hidden factor of Machine Lifespan, so you don’t overspend on power you don’t need.
