Integrated Transformer (IT) guns are more efficient than separate-type (Cable guns).
Separate-type guns place the transformer away from the gun, causing long-cable power loss and only 50–60% efficiency. IT guns house the transformer inside the gun, minimizing loss and delivering the same output with smaller capacity.

X-type guns are suited for horizontal welds, while C-type guns are ideal for vertical welds.
X-type (A-type) resembles pliers, with short arms that are flexible and long arms designed to reach deeper into the workpiece. C-type (Push guns) clamp in a straight line, making them effective for vertical welds.

The maximum arm length designed so far is 1200 mm. The arm can be customized in length, angle, and shape according to the workpiece, but the longer the arm, the higher the current loss.

Microprocessor controllers are more precise and flexible than traditional digital types.
They provide accurate current and time control, support multiple parameter settings, and feature constant current monitoring for stable weld quality. Digital controllers allow only basic adjustments with less flexibility.

Standard cable length is up to 3 meters; longer distances require custom design.
keeping the cable under 3 meters ensures stable welding current. For longer reach, a custom solution is needed.

Yes, aluminum can be spot welded by using an DC inverter spot welder.

Yes, by using a flat electrode or universal (swivel) welding tip, the weld surface can remain flat without dents.

Aluminum-copper caps provide high thermal stability, anti-sticking performance, and superior conductivity, which extends electrode life. Because aluminum oxide (Al₂O₃) is insoluble, it prevents zinc adhesion when welding galvanized sheets, reducing electrode wear.

Yes, all cutter blades and holder in the tip dresser can be replaced by the user.
This design allows easy maintenance, reduces consumable costs, improves efficiency.

Electrode replacement depends on welding parameters, usage frequency, cooling efficiency, and material type.  Actual lifespan varies with production conditions, and electrodes should be replaced when worn to ensure consistent weld quality.

Yes, welding tests are available in most cases (special machines excluded).
Customers can supply workpiece samples, and welding tests will be carried out to verify results.

A DC inverter spot welder offers more stable output, faster welding speed, and more precise heat control. Compared to AC types, it avoids uneven welds, increases efficiency, and is suitable for welding sensitive metals.
