3.2 Brief Description of Product Parts
① QBH Module: Locked connection between QBH fiber tip and handheld
welding head;
② Collimation Module: Convert the diverged beam into parallel beam;
③ Wobbling Focus Part: Focus the parallel beam into a spot and control
the wobbling trajectory of range 0~5mm;
④ Focus Protection Window Cartridge: Avoid dirts from entering onto the
focus lens, which can extend the service lifespan of focus lens;
⑤ Welding Protecion Window Cartridge: Prevent the dusts and spatters
entering the head and protect the focus lens;
⑥ Gas Blowing&Focusing Module: Adjusting focus, and blowing gas to
prevent the workpiece from being oxidized, by destroying the laser effect
on the workpiece surface of the ionosphere to form isolation the workpiece
and air.

For collimation length F50mm and focus length F150mm
Attention
Attention
1.Ensure standard and reliable grounding before power on;
2.Clean the QBH fiber tip carefully before connect it to the
welding head as any dirst and dust would caused optics
burned inside;
3.Clean and dust-free environment is required when
replacing protection window.
4.LHSW200 welding head is not allowed to work without
water cooling;
5.Hot plugging is forbiden;
6.Ensure the red light comes out of the nozzle before firing
the laser;

Attention：Gas should be filtered and dried otherwise the
protective window would be contaminated and damaged.
① Gas connector shoule be connected with φ6mm hose and input
protective gas, with suggested input flow ＜30L/Min, which will protect
the weld material surface and extend the lifespan of protective window.
High purity of N2 and Argon gas is suggested to process

Due to the different datum of every laser source,
here we introduce methods to find the focus
point:
a) Loosen the part ①, fit the tube part ② where
the smallest point of red light appears ( this
point does not coincide with the laser focus)
b) Turn off the ‘PE Protect’ in control panel and
set the laser power at 150W approximately.
Then aim the hand-held welding head at the
stainless steel sheet and, point the laser and
move the head up and down. The focus point is
where the spark is greatest;
c) To set laser power to 250W around and
operate in the same way with alumium sheet
instead of stainless steel will help find the focus
point more precisely.
