8. POOR WELDS / TROUBLE SHOOTING
If the welded seam contains holes, the upsetting pressure should be increased, the welding current
reduced or both settings changed. We must emphasize once again that proper welds cannot be
made if the blade ends are not cut square, and properly cleaned. Welding of blades may take
practice, do not be discouraged if your welds are not perfect at first.
Avoid overlapping when welding thin blades. If welder does not give suitable weld, check in coming
voltage to the machine. If voltage is low, use next blade size setting. Example: 220 volt machine,
incoming voltage is 208 volt, to weld 1/2” blade use 5/8” settings.
If incoming voltage is high reverse this procedure.
If incoming voltage is low, the welder transformer has taps that can be set to a 10% increase or
decrease. SHOCK HAZARD! ONLY A QUALIFIED ELECTRICIAN SHOULD ATTEMPT THIS.
ALWAYS CONTACT DAKE BEFORE REMOVING THE WELDER.
If the welder does not shut off, after the welding cycle, or will not start the welding cycle, a limit switch
adjustment is needed.
THE WELDER MUST BE REMOVED FOR THIS ADJUSTMENT. SHOCK HAZARD! ALWAYS
CONTACT DAKE BEFORE REMOVING THE WELDER OF MAKING INTERNAL ADJUSTMENTS. A
QUALIFIED ELECTRICIAN MUST DO THESE ADJUSTMENT.
MACHINE MAINTENANCE
The maintenance of the machine is naturally based on the usage rather than a time element.
The following is a recommendation based-on-average usage, and adjustment to the frequency
can be made on an individual basis. See below graphic for locations.
• Chip Pan - clean - as required.
• Band wheel tires - remove embedded chips -
weekly.
• Blade guide assemblies - clean - weekly.
• Gear box - drain and refill - yearly
• Monitor Hydraulic Reservoir.
• Drain water from water trap on air regulator
weekly.
Note: If raising the guide post more than half way up
from the table, and guide post cranks up hard, the
upper blade guard must be removed. See figure A&B
Blade will still be contained in the upper position.
