I thought I was getting a hold of the holy grail when I ordered it but, after a dozen tries with it I'm VERY hit and miss. I use it for clear but, I'll save my questions till I know someone has used it with success |

I started with a chinese 1.3 gravity and wasn't happy with the finish so I ordered the Iwata w-101.131 then while waiting for it to arrive did one more helmet flawlessly with the Chinese gun. the comp. is about 3.7 cfm (which is too low) I use sikkens HS clear with a slow reducer. I have a mini reg on the gun which I've tried @ 14psi up to 30 psi. It just seems every time I spray I have to move 30 cm in 10 seconds to get a smoothish coat but run the risk of runs on the second coat. What works for you? |

I "fink" Therefore I am!

Oh dear..... Looks like it was expensive too! Did someone advise you to get that particular gun? I used a cheap old £9 suction gun for a while, when I used 1K. When I went over to 2K, I just asked Paul (artspray) what he recommended, as he is in the trade! Followed his advice, bought secondhand RP 3000, job done! For not a lot of money..... Try to find someone else that is using one, follow their setup. |

Yeah I'm talking about this to Paul on KKL right now also. When I told Coast what I was looking for the guy recomended it ( I was looking at a minijet) I know I could use a better comp. but $$ is scarce these days. yeah, if I could find out what pressure people have gotten good results with it would be a start. |

hi ,i know i have run through this on KKL but now i know what size compressor your useing i can say its a touch too small and you want a 2 HP unit minimum ,that gun will use around 5CFM at a guese and your compressor will not keep up with it for long ,a good 2HP comp will give between 8 and 11CFM the W101 with a 1.3 set up is capable of clearing the side of a small car and is about as good as a Sata minijet so getting another gun isnt going to solve your problem ,the other way out of this may be to order a smaller set up for the W101 say a 1.0 or near to that but in all honesty you could use the fluid control /needle stop to reduce the paint flow and at the same time reduce your fan which coincidently will also make the gun use less air  my friend as i said on KKL uses the W101 gravity and a W100 suction that i suplied both 1.3 but the W101 gravity puts on more material i have a feeing its lack of experiance thats creating your problem more than the equipment but your compressor isnt helping much either with 2K clear you need to let the first coat tack off for about fifteen minutes before aplying a heavier second coat however HS clears can be aplied one coat that slow reducer is for oven conditions and i would recomend you go for at least a medium if not a fast reducer ,in fact go and get yourself some fast reducer and you can mix them untill you get something that suits but in airdry conditions i would be spraying with a fast reducer and hardener unless its very hot day and flow is being effected hope this helps but if you need any further advice PM me and you can have my tel no so i can advise you better rgds Paul |

Hey that stuff is helpful even though it wasnt my problem.  your post made me want to ask though, Is there a set use for fan spraying as opposed to cone shape? I have adjusted my gun to get a nice layering and overlap that works for me, But now its set i just never adjust it. Am i "supposed" to have a fan shape for some things and a cone for others? |

Hey hey Paul, Thanks again! I'm not a total newb but your right I have 2 years at about 60 pieces experience and very new to the W101. the comp says it is: 1.5 hp,Disp. 101 l/min which I converted (?!) to 3.7cfm and a 25L tank. I'm living in Taiwan so heat is always an issue and so is humidity sometimes. I just figured out the 15 min tack time two days ago. Here's a picture of what I got at 20 psi, 1/4 fan and 2 rotat. of fluid and 5-6 cm away at 9 sec/Ft travel. Totally akward from my cheapie style and prone to runs. Cheers Paul, I'm going to do some more practising with all the new insight before I go bothering you and hopefully I can get a larger comp soon. |

the picture isnt too clear but that comp is too small ,at 9 secs per foot it sounds like either your material flow is a touch too limited or your material is too thick ,remember HS clear needs more reduction through a touch up gun such as the 101 ,i would switch to a medium reducer or even a fast but use 15% to 20% even up to 25% then take your gun further off the job and increase your speed on small items you can use the gun on a full round pattern which will substantialy reduce air consumption but remember to also reduce the air pressure as the gun will blast all the available air through the nozzle opening with the fan diverter turned off ,the gun will then act like a big airbrush ,just play around some more with both the gun and your clear and im sure you will get this right Paul |

you reduce your fan to suite the aplication ,say you need to do the wing rails or door shuts then you use the round fan pattern but reduce your airpressure ,as i stated with the fan diverter shut off all the airflow is directed through the nozzle hole so it will increase the amount of material being pulled though ,the term for this is putting your gun on a "jet" i have used full size guns to do very detailed work with the fan turned off and the air pressure turned down ,they then act like a big airbrush the other use for a cone pattern is blending work on small touch ups ,you then work the gun in a circular motion pulling it away the further you go from the centre especialy with metalics and pearls to avoid a halo effect i have got specialist guns that have cone only aircaps[bell housing design] designed for such work Paul |
