Wattsan FL HH

Wattsan markers use laser sources from Raycus, JPT and MAX Photonics — the leading Chinese manufacturers whose components are used in machines from TRUMPF, IPG and Coherent. The R series (standard fiber) delivers consistent power for deep engraving and annealing. The J MOPA series (JPT M7) adds pulse width control from 2 to 500 ns, enabling color marking on stainless steel, black marking on aluminum, and fine detail at very low power without burning.

All Wattsan markers use F-theta (flat-field) scan lenses that maintain constant focus across the entire working area — unlike standard lenses where corners defocus. The galvo-driven scanning mirrors move the beam at speeds up to 8000 mm/s, achieving marking cycle times measured in seconds. Standard field sizes: 100×100 mm, 150×150 mm, 200×200 mm, 300×300 mm — selected based on application requirements.

The FL (fiber laser) series operates at 1064 nm wavelength, absorbed efficiently by metals. It marks stainless steel, aluminum, brass, copper, carbon steel, titanium, gold, silver, and also anneals tool steel to black without material removal. At higher power it deep-engraves. Non-metals: leather, rubber, some plastics. The MOPA variant (J series) adds color marking on stainless steel and fine grayscale on aluminum.

The FL HH detaches the scan head from the control unit, giving a portable marking tool for objects that cannot be moved to the machine — fixed machinery, large structural steel, vehicles, pipelines and building components. The handheld head is connected via flexible cable, weighs under 2 kg, and covers a 220×220 mm field. Marking quality is identical to the stationary version. Ideal for traceability, serial number marking and asset labeling in the field.
