The CD-700 stud welder from Midwest Fasteners is designed specifically for the insulation contractor. In fact, it is one of the most powerful capacitor discharge units available today. The CD-700 features a separate cup head weld pin contact mode that welds to materials as thin as 20 gauge – without fear of burn through. A unique feature is the 84,000 to 1,68,000 MFD variable capacitance high/low power range switch which handles the toughest applications. The high power range helps eliminate surface preparation when welding “Power Tip” pins from Midwest Fasteners.

The unit’s solid state circuitry lowers maintenance costs, since moving part are eliminated. And the rugged steel chassis makes the CD-700 able to withstand the rigors of construction job sites. Gauges and control knobs are protected by a recessed control panel. Circuit breaker protection prevents expensive repair to component parts, such as printed circuit board. The auto fault shut off adds to operator safety, and the panel meter displays capacitor discharge voltage at a glance.

An ultra-light 24 ounce precision Contact Gun is included with the CD-700 systems. With this Gun,operator fatigue is reduced-thereby increasing production. The weld gun also features interchangeable main spring pressure that is necessary for many special welding application and critical in welding aluminum fasteners and dissimilar material. The unique drilled through gun shaft enables precise gun set up for welding aluminum pins and extra long CD weld pins.
