Core Advantages — Why 520 g·cm Matters

• Faster, more efficient color packing: High torque reduces passes and minimizes skin trauma.

• Stable needle performance under load: Keeps consistent depth with large needle groups and dense fills.

• Cleaner, steadier lines: Better control for long lines and geometric details.

• Reliable at lower voltage: Maintain penetration and save battery life during wireless use.

• Smoother feel, less hand fatigue: Lower vibration and stable output improve operator comfort.

Stroke Recommendations 

• 2.2 mm: Fine shading / permanent makeup / SMP

• 2.6 mm: Soft shading & subtle gradients

• 3.0 mm: All-rounder — balance between liner & shader

• 3.4 mm: Stronger shading / medium packing

• 3.8 mm: Line work (liners)

• 4.2 mm: Heavy packing / large color fills

Who This Is For

• Professional tattoo artists and busy studio shops needing high-throughput filling.

• Traveling or guest artists who require reliable wireless performance with wired backup.

• Artists who demand predictable needle behavior for detailed linework and bold color.

FAQ (concise)

Q: Is this a brushless motor?
A: No — the Soldier Pro 520 uses a coreless motor (not brushless). Coreless technology provides lower rotor inertia and faster response, contributing to higher usable torque and smoother feel.

Q: Will it work with my cartridge needles?
A: Yes — compatible with standard cartridge needles and studio RCA setups.

Q: How long does the battery last?
A: Approximately 6–7 hours at 8V under typical use; actual runtime depends on workload and voltage settings.
