Precautions before start-up of the GWT C9
CAUTION
The precautions below should be observed before proceeding with start-up of
the GWT C9:
• Make sure correct water flow values are defined. This to avoid damaged
welding equipment such as transformer, diodes, leaf shunts and other parts
of secondary side.
• Make sure power supply corresponds to the type plate at transformer.
• Make sure that the electrical power cable fulfills international safety
regulations.
• Make sure the electrical circuit diagrams and flow charts, delivered with the
welding gun, have been followed during installation.
• Make sure duty cycle does not exceed 40% for the primary side by calculating
Duty Cycle Rectifier. See how to calculate in the below example:
Duty Cycle Transformer = (weld time x welds/min x 100%)/ (60 s/min x
frequency) = (22 cy. x 10 welds/min x (100)) / (60 s/min x 50 hz) = 6,1%
Duty Cycle Rectifier (diodes) = (22cy. / (22cy. on + 150 cy.off)) x 100 = 12,8%
