ESAB CUTMASTER 60
For optimum smooth surface quality, the travel speed should be adjusted so that only the leading
edge of the arc column produces the cut. If the travel speed is too slow, a rough cut will be produced
as the arc moves from side to side in search of metal for transfer.
Travel speed also affects the bevel angle of a cut. When cutting in a circle or around a corner, slowing
down the travel speed will result in a squarer cut. The power source output should be reduced also.
Refer to the appropriate Control Module Operating Manual for any Corner Slowdown adjustments
that may be required.
Piercing With Machine Torch
To pierce with a machine torch, the arc should be started with the torch positioned as high as possible
above the plate while allowing the arc to transfer and pierce. This standoff helps avoid having molten
metal blow back onto the front end of the torch.
When operating with a cutting machine, a pierce or dwell time is required. Torch travel should not
be enabled until the arc penetrates the bottom of the plate. As motion begins, torch standoff should
be reduced to the recommended 1/8 - 1/4 inch (3-6 mm) distance for optimum speed and cut quality.
Clean spatter and scale from the shield cup and the tip as soon as possible. Spraying or dipping the
shield cup in anti - spatter compound will minimize the amount of scale which adheres to it.
