Troubleshooting - GYS Toparc TPT 40 Manual De Uso

TORCH PARTS
The torch shall be equipped with suitable consumables. They shall be chosen according to the cutting application and the cutting current value.
Inappropriate parts may drive to cutting defects, untimely wearing of consumables, and even malfunction of the whole cutting system.
Consumables
Periodicaly check the wearing level of the protection nozzle, tip and electrode. To be checked also in case of significant reduction of the cutting speed.
We advice to replace together nozzle and electrode.

TROUBLESHOOTING

SYMPTOMS
No arc striking
Interruption of cutting arc
Untimely wear of consu-
mables
Excess of barbs underneath
the parts after the cutting
The cut groove is not
perpendicular to the metal
sheet surface

Nozzle
Replace the nozzle when it looks damaged (traces of burns).
Clean the inner part of the nozzle if clogged or dirty.
Replace the tip if the inner diameter is enlarged or distorted.
To be replaced if lateral openings are clogged.
To be replaced if an important cavity appears on the center.
Consumables are wear parts, it s important to know when to replace them.
Visually: welded or damaged consumables, tip hole larger than 1.5mm, weared electrode, welded pads...
Consequencies: loss of cutting performance, arc striking difficulties...
The nozzle shall be properly tightened so that all parts are correctly fixed. The nozzle shall not be easily turned.
Use compressed air with oil and water filtration.
POSSIBLE CAUSES
Torch incorrectly plugged on the generator.
Unsuitable pressure of compressed air.
Missing consumable part (nozzle, tip, electrode,
diffuser)
Assembly defect of consumables.
Earth clamp not properly clamped (if interruption after
a few seconds of cutting)
Unsuitable cutting speed.
Too important distance between the torch nozzle and
the part to be cut.
Disruption of compressed air feeding.
Damaged consumable inside the torch.
Insufficient air pressure.
Too fast cutting speed.
Impurities or humidity in compressed air.
Surface of the part to be cut too dirty.
Cutting speed too fast.
Unsuitable pressure of compressed air.
Insufficient setting of the cutting current value accor-
ding to the thickness of the metal part to be cut.
The torch is not kept perpendicular to the surface of
the part to be cut.
Consumable not properly assembled inside the torch
(untightened nozzle...)
The setting of cutting current is too small according to
the thickness of the part to be cut.

SOLUTIONS
Check the torch connection on the generator.
Set the air pressure to the recommended value.
Replace the missing parts.
Electrode is not in contact with the tip. Rectify the
assembly of all consumables.
Check that the earth clamp is connected on a properly
stripped area of the metal sheet.
Adjust the cutting speed.
Keep the torch close to the part.
Check the feeding of compressed air.
Inspect the torch consumable parts and replace them.
Adjust the air pressure.
Adjust the cutting speed.
Check the air filter on the generator.
Clean and strip the surface of the metal sheet.
Adjust the cutting speed.
Adjust the air pressure to the recommended value.
Adjust the setting of the cutting current value on the
generator.
Improve the handling of the torch.
Rectify assembly and tightening of consumables.
Adjust the setting of cutting current on the generator.
