PowerPinner® 7250

Heavy Duty - Benchtop Duct Lining Hand Welder

 

Fasten Ductwork With Strength, Reliability, And Efficiency

The PowerPinner 7250 Welder is a solid state resistance welder designed specifically for welding a resistance weld pin to galvanized sheet metal ductwork and insulation. With this benchtop welding array, set up shop on any stable surface and fasten insulation with high quality welds. Rely on the strong and durable welding unit that can stand up to a variety of jobs including 3inch liner.


Features Include:

Solid State Time & Weld Relay

Assures high quality welds each and every time.

High Capacity Transformer

Allows for continuous use for jobs of any size, including 3” Liner.

Weld Rate

15-20 pins per minute continuously. Faster rates are possible based on the operator.

Cables

Gun - 15 feet, #4/0 weld cable adn #16/3 control cable.
Ground - 5 feet, #4/0 weld cable terminating in a spring loaded, copper alloy clamp.

Capability

Welding 1/2" - 4" weld pins to 26 - 16 gauge sheet metal.

PowerPoint® Weld Pins

For peak performance, it is highly recommended using Gripnail's wide range of PowerPoint weld pins. Each point is precisely formed to provide optimum weld current.

A PowerPoint Weld Pin permanently attaches insulation to galvanized steel in the fabrication of HVAC duct work and withstands a tensile pull of at least 120 pounds from sheet metal.


Additional Features

High Capacity Transformer

The PowerPinner 7250 was completely designed around the same high capacity transformer that can be found in Gripnail’s floor model line of PowerPinner welders. This delivers the same level of power and quality welds commonly seen in much larger machines.

Pistol Grip Weld Gun

The weld gun has a pistol grip style handle with a trigger guard and switch for a more ergonomic working environment. Welding current is not available at the gun until the weld pin contacts the sheet metal and the trigger is pulled.

Chamfered & Recessed Weld Tip

The magnetic weld tip is specially designed with a chamfered edge and recessed center to optimize the weld quality of PowerPoint weld pins. The unique characteristics of the PowerPoint weld pin’s noninvasive protruding shank captures and centers the weld pin to ensure consistent loading, while the beveled retaining cap prevents it from shifting off the weld tip when the pin is being set through the insulation. Although the PowerPinner 7250 works with a variety of weld pins, our PowerPoint’s precision manufacturing process assures a trouble free operation with the best quality weld possible.

Low Maintenance

As a result of the PowerPinner 7250 solid state circuitry and design, it requires less maintenance.

Simplified Controls

A well defined Weld Time control is provided for simple adjustment when changing weld pin sizes or sheet metal gauge on different insulation jobs.
An easy to read, LED light clearly indicates the power status of the welder, while a different LED provides the welding operation status.
To activate the welder, simply pull the trigger on the Pistol Grip and the welder will engage.

Safety - A high visibility power switch comes standard with a simple to use Lockout/Tagout feature.
