J20-SC — the bigger, mains-powered handheld marker
Bigger field, more power, and a cable. The J20-SC is the plugged-in big brother of the SCII.
In one paragraph
What the J20-SC actually is
The J20-SC is a mains-powered handheld fibre laser marking machine with an 80×80 mm or 120×120 mm marking field, a 13.3-inch Windows console, a handheld head of about 2.1 kg, power draw of 500 W or less, and a 25 kg wheeled trolley case.

J20H-SCII vs J20-SC
Same marking platform, two different answers to "where does the workpiece live".

| Handheld head | ≤ 1 kg | ≈ 2.1 kg |

Core features
What four times the field buys you
120 × 120 mm field
Four times the area of a 50 mm field. Large logos, whole-part marking and multi-part fixtures fit in a single pass.
13.3-inch Windows console
Full marking software, real file management, network and USB. If your team already works in Windows, nothing new to learn.
≈2.1 kg handheld head
Heavier than the SCII's gun, and still light enough to position by hand on a fixture or a large part.
25 kg trolley case
The whole system rolls. One person moves it between benches; no lifting.

Choose between the two in one minute
- If the machine has to travel to the work — racking, installed pipework, outdoor structures, customer sites — take the J20H-SCII. Battery, 6 kg, one kilogram in the hand.
- If the work comes to a bench and you need a bigger field or higher throughput — take the J20-SC. Four times the area, Windows software, and it never runs out of battery.
- Neither is a deep engraver. Both are marking platforms. If you need to remove material, you need a different class of machine and we will say so.
FAQ
J20-SC questions
What is the difference between the J20-SC and the J20H-SCII?
Power source, weight and field size. The SCII is battery-powered, 6 kg total with a 1 kg gun and a 50×50 mm field — built to travel. The J20-SC is mains-powered, 25 kg in a trolley, with an 80×80 or 120×120 mm field and a 13.3-inch Windows console — built for a bench with more coverage.
What is the marking field?
80 × 80 mm as standard, or 120 × 120 mm as the larger option. Choose by the largest single graphic you need in one pass; anything bigger gets split, which costs time and alignment.
Does it need special power or air?
No. It draws 500 W or less from an ordinary socket. No three-phase, no compressed air, no external chiller.
Can it be moved between workstations?
Yes — the whole system is a 25 kg wheeled case. One person rolls it. That is mobility of a different kind from the SCII: it moves between benches rather than travelling to site.
How do I get a quote?
Message +86 137 0255 6158 on WhatsApp with the material, the field size you need and what you are marking. We quote both configurations so you can compare.
Need to mark on site instead?
The J20H-SCII runs on battery, weighs 6 kg and marks at 50×50 mm wherever the part happens to be.
