Tecna 7902 Portable Spot Welder - 2.5kVA Pulse (230V) - with Case & Accessory Kit

TECNA 7902 is a 2.5 kVA (at 50% duty cycle), semi-automatic, handheld, light-duty spot welding gun, perfect for a variety of general maintenance applications.

Furthermore, this high-performance pulse spot welder is suitable for up to 0.098 in. + 0.098 in. (2.5 mm + 2.5 mm).

TECNA 7902 Features

• Manually operated, no air or water lines to encumber movement.
• Versatile portable spot welder for auto body repair shops and maintenance shops.
• Synchronous built-in electronic timer with SCR from 2 to 65 cycles.
• Compensation circuit starts the timer only when there is a proper passage of current, which enables to perform on oxidised sheets, on surfaces with paint residues or on black sheets.
• Current control with phase shift adjustment to carry out difficult welds, on very thin thickness, on rods with reduced diameter, on stainless steel sheet and similar.
• Force adjustment with scale in daN.
• Additional arm couplings to provide larger opening between arms.
• All transformers are coated with F class insulation material. Tests are made using 4000 volts.
• Max weld current approximately 6,000-Amps (with shortest arms, narrowest gap).
• 3.7 in. (94 mm) gap between the arms.
• 0.87 in. (22 mm) diameter arms.
• Supplied complete with 4.9 in. (125 mm) long arms.
• Max electrode force with arm length L=4.92 in. (125 mm) is 120 daN (270 lbs.)
• Max electrode force with arm length L=19.69 in. (500 mm) is 38 daN (85 lbs.)
• Max 380 spots per hour (6 – 7 spots per minute, roughly need to wait 10 seconds between welds to dissipate heat).
• Choice of additional arm configurations are available (contact TECNADirect.com for more information).
• 0.47 in. (12 mm) diameter rod for electrodes standard.
• 220V/60Hz/1-phase
• Pulsation weld time control available (P version).
