Mechanized cutting issues
The torch does not cut
completely through the
workpiece.
• Make sure the system is set to cut mode, not gouge/marking mode.
Seepage51.
• Decrease your cut speed.
• Inspect and replace the consumable parts if they are worn or damaged.
See page 154. Always replace the nozzle and electrode together.
• Make sure that the torch is being used correctly. See Cut with the Hand
Torch on page 59.
• Make sure the consumables installed on the torch match the selected
mode. For example, do not use gouging consumables when the system is
set to cut mode. See page 51.
• Increase the output current (amperage) on the plasma power supply.
Seepage51.
• If the output current cannot be increased, determine if the metal being cut
exceeds the maximum capacity for this system. See Cutting specifications
on page 22.
• Clean the area where the work clamp contacts the workpiece. Remove
any rust, paint, or other residue. Make sure there is good metal-to-metal
contact.
• Inspect the torch lead. Straighten it out if it is twisted or kinked. Replace it
if it is damaged.
• Check the gas pressure and the gas supply hose. See page 140.
• Adjust the gas flow rate. See Gas supply source on page 35.
Problem Solution
The machine torch does
not fire an arc. Instead,
the torch blows out short
puffs of air and the power
supply sounds like it is
releasing pressure.
• The first time you send a start signal to the torch after you set the
torch-disable switch to the “ready to fire” ( ) position, the torch may
emit multiple puffs of air in quick succession. With each puff of air, the
torch vibrates slightly, and plasma power supply emits a pressure-release
sound. This is a warning that occurs when you lock and then unlock the
torch without turning OFF the power supply. (The Torch Cap LED also
illuminates – see page 148.) This does not indicate a fault condition.
The purpose of the warning is to alert you that the torch is activated and
will fire a plasma arc the next time it receives a start signal. See page 45.
The torch’s pilot arc
initiates but does not
transfer to the workpiece.
• Clean the metal surface of any rust, paint, or other residue that may
prevent a good metal-to-metal connection.
• Make sure that the work lead is making good contact with the cutting
table.
• Make sure that the cutting table is properly grounded and is making good
contact with the workpiece.
• Decrease the torch-to-work distance (cut height). Refer to the cut charts
starting on page 121.
