Power Supply: The BT-DC Controller requires a stable single-phase 220V AC power source.

Electrical Symmetry: The single-phase line must be strictly symmetrical with respect to Earth Ground.

Extension Cord Quality: Use only heavy-duty, undamaged extension cords of verified quality and condition to safeguard personal safety and maintain consistent ETW (Electric Torque Wrench) motor performance under load.

SITE PREPARATION & ELECTRICAL REQUIREMENTS

CRITICAL
PRE-USAGE CHECKS FOR BT-DC CONTROLLERS

Before commissioning your BT-DC electric torque wrench on-site, verify the following electrical and power supply parameters to ensure optimal tool performance and operator safety:

How the BT-DC Digital Control System Works

THE SCIENCE OF DIGITAL PRESET TORQUE REGULATION.

Operating a heavy bolting system requires absolute precision to prevent under-torquing or catastrophic flange blowout. The Boltorq BT-DC series simplifies complex joint assembly through an intelligent micro-processor workflow:

Step 1

Digital Value Input

The operator uses the drive-mounted control unit’s up/down buttons to input the exact required torque value in single-unit increments, monitored live via the LCD screen.

Step 2

Dual Mode Protection

SET and RUN modes are separated to prevent accidental trigger engagement while configuring the tool on-site.

Step 3

Jerk-Free Soft Start

Upon pressing the single operating trigger, the motor initiates a soft-start cycle, feeding smooth rotational force without placing a sudden impact jerk on the technician.

Step 4

Automatic Shut-Off

Once the precise numerical preset value is achieved, the wrench automatically halts operation, ensuring repeatable clamp loads every single time.

FIELD ENGINEERING

ENGINEERED FOR CRITICAL GLOBAL INFRASTRUCTURE.

From offshore wind installations to high-pressure refinery turnarounds, the BT-DC series is built to perform where hydraulic hoses and pneumatic compressors fail.

Wind Energy Generation

Wind Energy Infrastructure

Securing tower base sections, gearbox housing blocks, and alternator pillow blocks where space is constrained and uniform torque is mandatory.

FREQUENTLY ASKED QUESTIONS ABOUT
DIGITAL ELECTRIC TORQUE WRENCHES

What is the primary advantage of a digital electric torque wrench over a pneumatic impact wrench?

Pneumatic impact wrenches rely on sudden bursts of rotational impacts that cause high vibration, operator fatigue, and inconsistent torque delivery. The Boltorq BT-DC electric series utilizes non-impacting continuous rotation with micro-processor digital cut-offs, guaranteeing exact numerical accuracy.

What power source is required to operate the BT-DC series on remote sites?

The tools operate on a standard single-phase 220V–240V AC electrical supply (50–60Hz). Proper extension cord quality and symmetrical earth-ground connections are recommended for optimal performance and personal safety.

Are spare parts and technical support available globally?

Yes. As an independent manufacturer and exporter based in Jamnagar, India, Boltorq maintains extensive stock availability of standard products and replacement components for prompt global fulfillment.
