The CD700 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 CD700 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 168,000 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.
