A welding cable with a cross-section according to the table can be attached to the clamp by means of clamping screws. The clamping jaws are made of brass, which contributes to good conductivity of the welding current as well as proper service life. The clamping of the jaws on the material is carried out with a knob and a screw connection. The place of attachment of the welding cable with the body of the clamp is shielded by a rubber cover.. - maximum conducted current at 60% duty cycle - 600 A . - maximum thickness of crimped material: 30 mm - cross-section of electrical cable: 120 mm2 - handle weight: 850 g
