Hand cutting issues
Problem Solution
Pulling the torch trigger
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 pull the torch trigger 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 –
seepage148.) 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 you pull the trigger. See page 45.
The plasma arc sputters,
and consumable life is
shorter than expected.
• Make sure that the consumables are installed correctly. See page 46.
• Inspect and replace the consumable parts if they are worn or damaged.
See page 154. Always replace the nozzle and electrode together.
• Check the gas pressure and the gas supply hose. See page 140.
• Inspect the gas filtration system for signs of moisture. See page 141.
The torch does not fire an
arc after repeated
attempts. No issues with
incoming power or gas
supply are apparent. No
fault LEDs or fault codes
display.
• Test the torch-disable switch to see if it is working properly.
See page 152. Replace the switch if it is broken or not working correctly.
The plasma arc does not
transfer to the workpiece.
• 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 work clamp for damage. Repair or replace it if necessary.
• Move the torch closer to the workpiece and fire the torch again. See Cut
with the Hand Torch on page 59.
The plasma arc blows out
but re-ignites when the
torch trigger is pulled
again.
• Decrease the length of the arc stretch. Whenever possible, drag the torch
on the workpiece. See page 67.
• If you are using the Maximum Control gouging consumables, make sure
the system is set to gouge/marking mode and the output current is set to
26 – 45 A. Setting the output current below 26 A with these
consumables can cause the arc to extinguish.
• Inspect and replace the consumable parts if they are worn or damaged.
See page 154. Always replace the nozzle and electrode together.
• Make sure the incoming gas supply hose has an internal diameter of
9.5 mm (3/8 inch) or greater.
• Inspect the gas filtration system for signs of contaminants that may be
interfering with system performance. See page 141.
• If you manually adjusted the gas pressure before this issue occurred, reset
the gas pressure to the default setting. See page 56.
