3Mm Spot Welding Machine

3mm spot welding machine can weld 3+3mm stainless steel plates,

carbon steel plates, aluminum plates, copper plates and other materials

with high welding efficiency and precision.

Types of 3mm Spot Welders

AGERA’s 3mm spot welders are designed for medium-thickness metal sheets to create strong connections for customers. 3mm spot welders are widely used in modern industrial metal connections and are commonly used in industries such as automotive parts, sheet metal processing, hardware and home appliances. AGERA’s 3mm spot welders use advanced spot welding technology. First, the machines are highly adaptable and have low requirements for power grids. Second, the joints of the products they weld are strong and high-precision, making them ideal for 3mm metal connections.

Some of The Welder Model

Standard 3MM Resistance Spot Welding Machine

With a rated capacity of 260kva, it can instantly release a welding current of 60KA, and the working pressure can reach 10000N. It can be used for spot welding of most 2-3mm metal plates, and can also switch the round head for projection welding of nuts and bolts.

Can I use a 3mm spot welder to weld a 5mm stainless steel plate?

If you don’t have high requirements for the quality of the welded joint and don’t need high strength, you can use this machine to weld a 5mm stainless steel plate.

Do you need to add filler material constantly when welding?

You don’t need to add any material when welding most materials. Only when welding copper do we often add brazing material to ensure the strength of the weld.

What pressurization methods do these machines use?

Our 3mm welding machines are generally pneumatic spot welding machines, which use cylinder pressurization mode. We can also use other pressurization methods, such as hydraulic pressure, servo cylinder pressurization, etc.

Are these machines AC or DC?

DC spot welding machines, in order to ensure welding quality, our machines all use DC welding to meet the welding requirements of more materials.
