CUTTING TECHNIQUE
For best performance and life expectancy, always use the
correct and original parts for cutting torch.
1.Install the cutting tip and set the output current.
2.Hold the torch away from your body.
3.Slede the trigger release toward the back of the torch
handle while simultaneously squeezing the trigger. This will
activate a pre-flow of air foe 2 seconds before the pilot arc is
turned on followed by the plasma arc.
4.Start moving the torch across the work piece and observe
that the arc penetrate the work piece.
5.when cutting is established pull the torch slowly across the
surface of the work piece.
6.pause briefly at the and of the cut before releasing the
trigger.
7.The plasma arc goes out immediately. Air continue to flow
15 seconds.
FOR PIERCING HOLES
With
UPC-85 ML
you can pierce metal with thickness up to
15mm.
1. Rest the torch tip lightly on the work piece at 45 deg.
Angle.
2. Press trigger on the torch handle. Air will flow for 2
seconds before pilot arc strikes.
3. When the plasma arc is established, slowly and one
smooth movement straighten the torch back to 90 deg.
Angle ensuring the arc penetrate the work piece.
4. Start moving the torch across the work piece and observe
that the arc continue to penetrate.
GOUGING
You can use this system with the gouging consumables for
gouging applications. (Check torch parts. The torch parts must correspond with the type of operation. Refer
to Section 5, Torch Parts Selection).
1. Hold the torch so that the torch tip is slightly above the workpiece before firing the torch.
2. Hold the torch at a 45° angle to the workpiece with a small gap between the torch tip and the workpiece.
Press the trigger to obtain a pilot arc. Transfer the arc to the workpiece.
3. Maintain an approximate 45° angle to the workpiece as you feed into the gouge.
Push the plasma arc in the direction of the gouge you want to create. Keep a small distance between the
torch tip and the molten metal to avoid reducing consumable life or damaging the torch.
You can vary the gouge profile by varying the:
-Speed of the torch over the workpiece.
-Torch-to-work standoff distance.
-Angle of the torch to the workpiece.
Varying the gouge profile
Follow these recommendations to change the gouge profile as needed:
Increasing the speed
of the torch will
decrease width
and
decrease depth
.
Decreasing the speed
of the torch will
increase width
and
increase depth
.
Increasing the standoff
of the torch will
increase width
and
decrease depth
.
Decreasing the standoff
of the torch will
decrease width
and
increase depth
.
Increasing the angle
of the torch (more vertical) will
decrease width
and
increase depth
.
Decreasing the angle
of the torch (less vertical) will
increase width
and
decrease depth
.
