Product Description

The  Tecna 25kVA foot operated spot welder is equipped with digital microprocessor control (TE101). Engineered for precision, operator comfort, and consistent performance, it’s ideal for mid-volume welding tasks across automotive, metal fabrication, and industrial manufacturing sectors.

Key Features

  • Adjustable Pedestal & Arm Design
    Ergonomically crafted with adjustable arm lengths and foot pedal positioning for optimal operator comfort and flexibility

  • Advanced TE101 Microprocessor Control
    Features include phase-shift thyristor drive, selectable current ranges, storage for up to 99 welding programs, external program selection, pre-weld/ramp/pulse functions, weld/no-weld modes, current compensation, error signalling, and automation interface.

  • Water-Cooled, Durable Components
    Transformer, arms, and electrodes are water-cooled and the transformer is epoxy resin–coated for enhanced durability and thermal management.

  • Heavy-Duty Electrode Holders
    Chrome-copper holders support straight and angled electrode configurations for extended wear and adaptability.

  • Microswitch-Enabled Welding Initiation
    Welding initiates automatically once the predefined electrode force is reached, ensuring consistent weld quality.

  • Available with a 2 stage pneumatic pedal or a manual operated foot pedal.

  • Pre-connected for additional electric foot-pedal for the direct recalling of welding program No.2. This function is helpful when different kinds of welding are to be performed on the same piece.

  • Protected filter assembly with gauge.

  • The air operated lubrication free cylinder eliminates oil mist.

  • Arms: gap 280 mm, adjustable depth 320 mm.

Water cooler not included.
