Iwata LPH-400LV 1.3 gets my vote as it produces the thinnest slickest flattest coat of clear for me. It doesn't matter if the clear or paint is as thick as tar the gun breaks it up fine with only 20ish psi. I like to spray slow and controlled and apply the clear exactly how I want it- flat and slick with no urethane wave from pushing puddles and heavy hosing. Use slow reducers and hardeners, shoot for thin but slick/wet-this will produce the least amount of urethane wave and the best as sprayed gloss.
Some like the 1.4 tip and my gun came with a 1.4 but this unit puts out plenty of material with only a 1.3 - equal to most other designs using a 1.4 or 1.5 IMO... Even with the 1.3 tip my fluid adjustment is usually only 2- 2.5turns out as I see no need for the volume of a full trigger pull. JMO |

Bob, many have different standards for "slow". For me, the 1.4 on the Iwata is still kind of slow for large panels, that's why I was going to get a devilbiss plus but got a Sata rp 1.3 instead. I still love the LPH400, ordered the oranger cap for it last week!
To convert a 1.3 to 1.4 (or vice versa) for the iwata, the only thing to change is the fluid nozzle. You are right tough, 1.3 will work great but 1.4 is the "universal" tip size for clears. |

Up the psi
Iwata's got to be pushed up to 20-24 psi to get that great finish. Iwata recommends 16-20 but that wont cut it. I was having a problem with the 16-20 psi setting and got a tip to pump it up and to 20-24 and like magic it was glass. I think they give the 16-20 setting to be compliant as i've found no one that uses 16psi.....G

the only time I have had any problem was with Operator Error..OOPS I resemble that comment. I have yet to NOT get a great finish unless the Idiot behind the Gun was Faulty Funny when I went to the Dupont school awhile abck the day I brought my OWN Iwata the Instructor used it at 16PSI and got the perfect finish..... Iwata did their home work the LPH400 52F1 |

what differences are you going to notice at the different pressures? I've been using way more input pressure than the 18-24 lbs you guys are talking about.....what should i notice when i lower my pressure? I know they recommend 8-10 at the tip, but how do you get a reading on that?
You guys are really dialed in if you notice a difference from 18 and 22 lbs. |

Now at 10 PSI cap pressure you will have 18-23 psi at the gun with the LPH 400. This does not mean some will not get better results with Higher pressure because the Speed and distance at which you spray can affect the finish. people who hold the gun farther away or closer than the 4-6" recommended will use a different pressure to get the Same results. Also user speed can affect the way a gun sprays...You should remember that on an Iwata 10 Psi cap pressure will Always come with only 18-23 Psi at the gun...But then this is with Using a "Quality gauge"...At 23 Psi some gauges will read 24-29 Psi Air hose length and Diameter all come into play also...as well as Available compressor volume..... So bottom Line a Cap Pressure gauge is the only way you can be for sure of the required 10PSI at the cap Any more Inlet pressure causes Higher cap pressure which is Illegal and just causing more over sprayand wasted paint...So as you see...testing the pressure at the cap is the only way you can make for SURE of the cap pressure..CAP PRESSURE GAUGE And don't forget the Compressor Volume test....Spray Gun Volume control wide open..with no fluid in gun...trigger pulled all the way back..hold for TWO minutes..if the Compressor will not hold the required cap pressure for two minutes then you compressor is too small..some try to Cheat by turning up the pressure...may not always work Bottom line is you need to practice with your Spray gun whatever the brand to find the best pressure for you....taking into account all of the above. Find the Solution that fits your needs And I see we have another happy Iwata user..and it will only get better with practice and getting more familiar with the gun 52F1 |
