Problem

Reason

Check and solve

Acryl turns yellowish or bubbled after fire-polishing

1.       Flame temperature doesn’t match the material

2.       Material quality problem

1.     Add ethanol into gas filter (see user’s manual)

2.     Control the speed of fire-polishing well

3.     Change material

Red / yellow flame

Flame becomes wide & weak

1.       Impurities or water in torch

2.       Water in rubber pipe

3.       Ethanol over-mixed in electrolyte

1.       Clean up the torch and burn for a while

2.       Blow out the water in the pipe and check the gas filter

3.       Change electrolyte

Weak flame, barometer indicates 0.10mpa, ammeter indicates well

Gas clogged

1.       Check the rubber pipe

2.       Check the gas filter, adjust the spring valve if necessary

3.       Check the backfire fitting and torch

Weak flame, barometer indicates low, ammeter indicates well

1.       Gas leak

2.       Electrolyte losing efficacy

1.       Check the gas route

2.       Change electrolyte

Barometer and ammeter indicate zero

1.       Not electrified or fuse blowout

2.       Pressure switch malfunction

3.       If the indicate light bright, the electrolyte may lose efficacy

4.       Power box malfunction

1.       Check the wire and fuse

2.       Open the shelf to check

3.       Change electrolyte

4.       Let the pressure control wire short circuit and check the power box, or contact the manufacturer

With pressure but no current

1.       Gas exists in the machine

2.       Ammeter malfunction

1.       Check the machine

2.       Check the circuit, change ammeter if necessary

Pressure higher than 0.2mpa, rubber pipe may be blown off

1.                    Pressure switch malfuncyion

2.                    Safety valve malfunction

Contact the manufacturer if cannot solve

Backfire and explode inside

1.              Backfire-proof fitting malfunction

2.              Nozzle too big

Change torch or add backfire-proof fitting.

Contact the manufacturer if cannot solve
