PORTABLE SPOT WELDERS

HAND PORTABLE SPOT WELDERS 7900-7902-7903

Tecna hand portable spot welders 7900_2kVA

Tecna's improved and lightweight portable welding machine for car body shops.

Internal electronic timer from 2 to 65 synchronous cycles with SCR.

Compensation circuit that operates the timer only if current is circulating in the spot, which allows welding on paint- or oxidised sheets or on black sheets with the best results.

Force adjustment with scale in daN. 

Additional coupling in the lower arm to provide a large opening between the arms.

Class F insulated transformer, tested at about 4000 Volts.

FAQ and insights

Tecna electric spot welders are spot welders used to join thin metal sheets. They are particularly suitable for auto body, repair and light production in industry and crafts.

A.T.S. Lamberti offers three types of Tecna electric spot welders:

  • Tecna hand portable spot welder 7900_2kVA: this is the lightest and most compact spot welder, ideal for occasional work and in confined spaces.

  • Tecna hand portable spot welder 7902_2.5kVA: this spot welder is more powerful than the 7900 and has phase control for delicate work.

  • Tecna hand portable cooled portable spot welder 7903_6kVA: this is the most powerful and versatile spot welder, ideal for intensive and high cadence work.

Tecna electric spot welders work using the principle of electrical resistance. The sheets to be welded are placed between the two electrodes of the spot welder and an electric current is passed between them. The current generates heat that melts the metal of the sheets, thus creating a joint.

The advantages of using a Tecna electric spot welder include:

  • Precise and uniform welds

  • Possibility of welding thin sheets

  • Ease of use

  • Portability

  • Safety and reliability
