Your Single Source Stud Welding Specialists
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.
