Dross build-up on
parts of cuts
1. Tool/material building up heat
2. Cutting speed too slow or current too
high
3. Worn torch parts
1. Allow material to cool then continue cut.
2. Increase speed and/or reduce current until
dross is reduced to minimum
3. Inspect and repair or replace worn parts
Arc stops while
cutting
1. Cutting speed too slow
2. Torch is too high, away from material
3. Worn torch parts
4. Work piece earth cable disconnected
1. Increase speed until problem solved
2. Lower torch to recommended height
3. Inspect and repair or replace worn parts
4. Connect work piece earth clamp to work
piece or steel table.
Insufficient
penetration
1.Cutting speed too fast
2. Torch tilted too much
3.Metal too thick for plasma capacity
4. Worn torch parts
1.Slow down travel speed
2. Adjust tilt
3. Several passes may be necessary
4. Inspect and repair or replace worn parts
Arc sputters/flares
Water in the air supply
Install air drier or additional filtration
Consumables wear
quickly
1. Exceeding unit capability
2. Excessive ARC starting HF use
3. Improperly assembled torch
4. Inadequate air supply, pressure too low
5. Faulty air compressor
1. Material too thick, increase angle to
prevent blow back into torch tip
2. Do not operate HF ARC starting for more
than 3 seconds – you can also start with
torch in contact with metal or within 1/16”
of metal
3. See section ‘Replacing Consumables’
4. Check air filters, increase air pressure
5. Check air compressor operation and make
sure input air pressure is at least 100 PSI
Circuit breaker/fuse
trips while operating
Extensioncord being used is not heavy
duty
Use a heavy duty extension cord (2.5mm
diameter)
If you have any problems in setting up or operating the machine, please first re-consult this manual.
2.5 Operation environment
▲
Height above sea level
≤
1000 M
▲
Operation temperature range -10
〜
+40°C
▲
Air relative humidity is below 90 %( 20°C)
▲
Preferable site the machine some angles above the floor level, the maximum angle does not
exceed 15°C
▲
Protect the machine against heavy rain AND against direct sunshine.
▲
The content of dust, acid, corrosive gas in the surrounding air or substance cannot exceed
normal standard.
▲
Take care that there is sufficient ventilation during welding. There must be at least 30cm free
distance between the machine and wall.
