Cooper Hand Tools / Weller WECP-20 Soldering Station Power Supply

The Weller WECP-20 is a soldering station power supply that delivers stable, controlled heating power to compatible Weller soldering irons and stations. It provides continuous analog temperature regulation via potentiometer adjustment, enabling precise thermal control for temperature-sensitive electronic components. The unit operates at safe low voltage (24V AC) while isolating connected tools from mains power, making it suitable for both laboratory and production environments.

## Technical Specifications

• **Temperature Range:** 50°C to 450°C (continuous analog regulation)
• **Temperature Control Accuracy:** ±2% of setpoint
• **Heating Output:** 24V AC, 50/60 Hz, maximum 50W
• **Mains Input:** 230V AC (configurable for 120V or 240V)
• **Mains Fuse:** T 0.315A
• **Tool Connection:** 6-pin socket for Weller soldering tools
• **Dimensions:** 115 mm (W) × 150 mm (D) × 94 mm (H)
• **Weight:** 2.1 kg

## Key Features

• Analog potentiometer with visible temperature regulation control
• Green LED indicator showing regulation status
• Galvanic isolation of connected tools from mains at safe 24V AC output
• Antistatic design meeting ESD safety standards when paired with antistatic irons
• Compatible with 22 different Weller “Longlife” soldering tip shapes (ET-A through ET-H, tip diameters 0.8 mm to 5.6 mm)
• Available in codable or COD fixed-temperature versions

## Typical Applications

The WECP-20 serves applications requiring precise thermal control and electrical safety, including PCB assembly, rework of temperature-sensitive components, and ESD-protected work environments. Its ±2% regulation tolerance supports quality soldering in both bench and production settings.

## Compatibility & Integration

Designed specifically for Weller soldering irons including the LR-21 antistatic iron. The 6-pin connection socket accommodates a wide range of Weller tools. The standard tip type for the LR-21 is ET-B. Tool galvanic isolation and low-voltage operation ensure operator safety and component protection.
