Cordless Impact Wrench Gun

A cordless impact wrench gun is the fastest way to break stubborn bolts, snug down hardware, and keep fabrication moving without dragging cords across the floor.

At ArcCaptain, our cordless impact wrench guns are made for welders and metalworkers who want high torque, clean control, and grab‑and‑go power on the jobsite or in the shop. Think faster setups, fewer delays, and tools that keep pace with your welding workflow.

Power That Breaks Bolts Loose Without Breaking Your Flow

Short bursts of high torque save time when you are moving between tack, fit‑up, and final welds. These impact wrench guns deliver muscle on demand, so you stop fighting fasteners and get back to welding.

Brushless Motor Strength That Lasts

Efficient motors convert battery power into steady torque with less heat.

• Delivers strong breakaway torque for rusted or over‑tightened bolts
• Runs cooler for longer work sessions
• Extends tool life with fewer wear parts

High‑Impact Mechanism for Stuck Hardware

Controlled impacts loosen fasteners without constant strain.

• Reduces wrist fatigue during repetitive tasks
• Helps prevent rounded heads
• Keeps power consistent under load

Cordless Freedom That Fits Busy Weld Shops

No cords means fewer trip hazards around welding leads and gas lines. Grab the tool, step into position, and work where the joint is.

Portable Battery Power You Can Trust

Modern lithium batteries give steady output until the job is done.

• Consistent torque from start to finish
• Quick swaps keep downtime low
• Easy carry for field repairs and fab work

Compact Body for Tight Spots

Slim designs reach where larger tools cannot.

• Fits between frames and fixtures
• Easier access around clamps and jigs
• Better control in overhead or awkward angles

Built for Metalwork, Not Weekend Chores

These cordless impact wrench guns are made with welders in mind. Tough housings and smart controls handle dust, sparks, and daily use.

Variable Speed and Trigger Control

Fine control matters when threading bolts near fresh welds.

• Smooth starts reduce cross‑threading
• Adjustable speed for install or removal
• Better feel with gloves on

Durable Construction for Shop Life

Rugged materials stand up to real work.

• Impact‑resistant casing
• Reinforced drive components
• Designed for frequent, heavy use

One Tool, Many Jobs Around the Weld Table

From fixture setup to teardown, a cordless impact wrench gun earns its place fast. It supports the full metal fabrication cycle.

Handles More Than Lug Nuts and Anchors

• Fixture and jig assembly
• Structural bolt work
• Equipment maintenance and repair

Less Effort per Fastener Means More Welds per Day

• Faster prep before striking an arc
• Quicker breakdown after cooling
• Smoother workflow across projects

FAQs About Cordless Impact Wrench Guns

How do you use a cordless impact wrench?

A cordless impact wrench is used by selecting the right socket, securing it to the drive, and placing it squarely on the fastener. Squeeze the trigger gently at first to seat the socket, then apply steady pressure until the bolt loosens or tightens. Let the tool do the work and stop once the fastener is set to avoid over‑tightening.

What is the 20 rule for torque wrenches?

The 20 rule means you should not use a torque wrench below 20 percent of its maximum rated torque. Accuracy drops at very low settings, which can lead to uneven clamping force. For low torque needs, use a wrench designed for that range.

What should you not do with an impact wrench?

Do not use an impact wrench for final torque where exact specs matter. Avoid using damaged sockets, as they can crack under impact. Never hold the trigger down after the fastener stops moving, since this can strip threads or snap bolts.

Will a cordless impact driver remove lug nuts?

Yes, many cordless impact drivers can remove lug nuts if they have enough breakaway torque. Stuck or over‑torqued lug nuts may require a higher‑torque impact wrench. Always use impact‑rated sockets and keep the tool straight on the nut.

Can you overtighten bolts with a cordless impact wrench gun?

Yes, overtightening is possible because impact tools apply force in short bursts. This can stretch bolts or damage threads if you are not careful. For critical joints, stop early and finish with a torque wrench set to the correct spec.
