Portable and Precision Welding Guns
Serving North AmericA since 1983
Your Trusted Portable & Precision Welding Guns Supplier
High-Performance Handheld Welding Solutions for Every Application
The demands of modern manufacturing require equipment that is as versatile as it is reliable. Our selection of portable and precision welding guns provides the flexibility to bring the weld to the workpiece, rather than the other way around. At Spotco, we specialize in high-duty cycle equipment that ranges from ergonomic, rugged handheld units to ultra-precise micro-poke guns designed for the most stringent technical specifications.
Whether you are performing heavy-duty industrial assembly or working with thin-gauge components in the medical and aerospace sectors, we provide the specialized tools necessary for success. Our portable solutions are engineered to deliver consistent force and current, ensuring that "mobile" never means "compromised quality."
Precision-Engineered Portable Welding Solutions
We stock a diverse range of welding guns designed to meet specific industry standards and production duty cycles.
Industrial Handheld Welding Guns
Our handheld spot welding guns are built for the rigors of the production floor. These rugged, ergonomic units are designed to minimize operator fatigue while maintaining the high-duty cycles required for industrial manufacturing. Available in various throat depths and configurations, these guns are the "workhorses" of assembly lines, offering the durability needed for 24/7 operation.
Precision Micro-poke Guns
When accuracy is measured in microns, our micro-poke guns are the industry standard. These precision instruments are engineered for thin-gauge materials and delicate assemblies where heat control is critical. These units are specifically designed for applications where standard-sized electrodes are too cumbersome, providing surgical precision for intricate weld patterns.
Aerospace & Medical Grade Specifications
Our micro-welding equipment is trusted by the world's most demanding manufacturers. Our precision guns are approved for use under Boeing and Rolls Royce specifications, making them the premier choice for aerospace engine components, honeycomb structures, and high-reliability medical devices. When your project requires flight-certified or life-critical reliability, our precision guns deliver.
Customizable Tooling & Integration
Every welding project is unique. We provide a full range of interchangeable arms, specialized electrodes, and cable configurations to ensure your portable gun is perfectly balanced for your specific task. Our team can assist in integrating these guns with your existing Unitrol or MFDC control systems for seamless operation.
Unmatched Reliability for High-Stakes Manufacturing
Choosing the right portable spot welder is about more than just convenience—it’s about process control. Our guns are designed to provide repeatable pressure and current delivery, even in hard-to-reach areas. From the heavy-duty assembly of steel frames to the microscopic welding of aerospace sensors, Spotco provides the hardware that meets the highest standards of structural and electrical integrity.
PORTABLE GUN WELDERS
PW has been recognized as a world leader in portable spot-welding guns for many years. We have been supplying industries all over the world with equipment for both high- and low-volume production for over 40 years.
Heavy Duty Portable Spot Welders: for higher duty cycles (spots per minute) and heavier materials.
Cable Welding Guns: These are still used and are of particular benefit where very high duty cycles may be required.
Light Duty Spot Welders: for general-purpose welding on lighter gauge materials up to 1.5 mm.
POKE GUNS & PRECISION WELDERS
PW’s poke welders are used all over the world in aircraft, nuclear power, electronics, and other general industries. Approved by Rolls Royce and Boeing, the range runs from the small and portable B3 to the heavy-duty B70, used for more normal sheet metal applications.
On a thin gauge sheet, the poke welders can be used for manual seam welding using a roll spot wheel.
The precision welding systems provide very high accuracy for the welding of microcomponents. The DBZ100 will weld wire as fine as 1/100mm with its 4 kHz medium-frequency power supply. Weld forces from 0.5N to 180N are available from the BH weld heads.
ROBOT WELDING GUNS
The PW range of robot guns is designed for continuous operation under the most arduous welder production line conditions. Many automated lines operate 18 shifts a week, and the robot guns have to be able to withstand this heavy load.
The scissor welders guns are based around a high-tensile aluminum plate, giving strength with minimum weight. A range of throat sizes from 150mm to 450mm covers the majority of applications. Large robot guns are made from machined aerospace aluminum and can have arms up to 1 meter long. Splash covers are provided as standard, and Kevlar bags can be fitted, completely enclosing the welder's gun and keeping it clean, improving robot gun life and reducing service downtime.
Cylinders are manufactured from aluminum with honed, hard-anodized bores and have been tested over millions of cycles to ensure maximum longevity.
Servo welder gun options are also available, giving faster and quieter operation with improved weld consistency.
The C-gun range provides the same breadth, allowing use in any application. The robot guns are again fully self-equalizing, with a sophisticated slide system allowing easy movement and minimizing the possibility of component damage. A variety of sizes allow for the use of a huge range of electrode arms, all manufactured from chrome copper for maximum strength. Electrode tips and adapters can be selected to conform to user standards.
All the welding guns can be used with standard ISO transformer sizes. These range from 32 kVA to 103 kVA. For large throat sizes or specialized welding applications, medium-frequency transformer systems can also be used. These give unsurpassed weld quality as they deliver DC, ensuring a smooth input of weld energy.
A full range of electrode arms is supplied. Robotic applications are always designed to suit.

What is a micro-poke gun used for?
Micro-poke guns (sometimes called pencil or single-point welders) are used for very thin materials or assemblies where you can only access one side of the part. They are standard in aerospace and electronics manufacturing.
Can these portable guns be used with existing controls?
Yes. Most of our handheld and precision guns can be interfaced with your current Unitrol or other standard resistance welding controllers.
Are your guns suitable for aerospace titanium welding?
Absolutely. Our micro-poke units are designed for the precise heat and force control required for titanium and other exotic alloys common in aerospace.
How do I choose between an X-type and a C-type handheld gun?
The choice usually depends on the geometry of your part. C-type guns are great for reaching over flanges, while X-type (scissor) guns offer more versatility for deep-reach applications.
Do you provide the cables and balancers for these guns?
Yes. We provide high-flexibility kickless cables and spring balancers to ensure your operators can move freely and safely on the production floor.
Is training available for the micro-welding equipment?
Yes. We can include a Welding Seminar focused specifically on the operation and maintenance of precision micro-poke systems to ensure your team achieves flight-grade results.
