The CD-100 Capacitor Discharge Stud Welded from Midwest Fasteners is one of the most powerful units on the market today.
With solid state design, the CD-100 is perfectly matched to heavy-duty industrial fastening for welding larger diameter CD studs.

Not only can be CD-100 weld materials such as mild steel, stainless steel, aluminum and brass- the unit is also capable of welding
stud up to 3/8* diameter weld base. Due to the speedy capacitor discharge process, studs can be welded to material as thin as 020″
gauge without burning through.

The CD-100 comes equipped with a high/low power range switch that is helpful in welding small and large diameter fasteners. This
variable capacitance switch allows the operator to fine tune critical applications from 84.000 to 168,000 MFD. Anchor unique
feature of the CD-100 is the leo panel meter, which displays capacitor discharge voltage at a glance.

Solid state circuitry and rugged steel chassis assure durability and long service life. What’s more the unit is loaded with safely
features. Circuit breaker protection prevents expensive repair to component part, such as printed circuit board. The recessed control
panel protects gauges and control knocks. And the auto fault shut off aids in operator safety.

An ultra-light 24 ounce ‘precision Contact Gun” in included with the CD-100 welding system. With this gun, operator fatigue is
reduced – thereby increasing production. The CD-100 contact gun also includes interchangeable main spring pressure that is
necessary for many special welding application, and critical in welding aluminum fasteners and dissimilar materials.
