Product catalog summary

Overview: TECNA's resistance welding machines, models 4640N to 4649N, are designed for versatile spot welding applications. These machines feature an ergonomic column structure to enhance operator comfort and efficiency.

Main Technical Features:

Adjustable arm length for increased flexibility.
Durable chrome-copper electrode holders suitable for heavy-duty use, with options for straight or angled fitting.
Epoxy resin-coated transformer with water cooling for the transformer, arms, and electrodes.
Microprocessor control unit TECNA TE101 for precise welding current measurement and control.

Foot Operated Welders:

Adjustable electrode force with a microswitch to initiate the welding cycle at a pre-set value.
Length-adjustable foot pedal for operator convenience.

Air Operated Welders:

Lubrication-free pneumatic cylinder to prevent oil mist emission.
Adjustable electrode force via air filter reducer and gauge.
Semi-automatic drainage system for condensate.
Two-stage electric foot pedal for single and automatic cycle operations, ensuring correct piece positioning before welding.
Option to add a second foot pedal for dual time-current settings, useful for varied welding tasks on the same piece.

Accessories:

Water-cooled electrodes available on demand.
Various reduced-size brass and copper arms with different configurations for specific welding needs.

Performance:

Adjustable arm depth of 320 mm to suit different working requirements.
Maximum arm gap of 440 mm, intermediate gap, and minimum gap of 140 mm for diverse welding applications.

Specifications:
The document outlines the specifications for various types of spot welders, including foot-operated and pneumatic models. It mentions the maximum thickness of pickled mild steel that can be welded.

TE101 Weld Control Unit:
The TE101 is a microprocessor-based control unit designed for single-phase alternating current resistance welders. Its primary function is to manage the welder's components, particularly the controlled diodes that regulate the welding current. The TE101 supports up to 99 different welding programs, with 31 accessible directly from the external interface. It measures and controls the welding current within set limits and is compatible with both manual and pneumatic welders.

Programming and Control:
The TE101's work cycle is defined by 13 programming parameters, allowing for precise control over the welding process. This flexibility makes it suitable for a wide range of welding applications.

Manufacturer Information:
TECNA S.p.A. reserves the right to modify its products without prior notice. The company is based in Castel San Pietro Terme, Bologna, Italy, and provides contact information for sales inquiries.

Note:
Specifications and product details are subject to change without notice.
