Spray problems

[Drains]

Evening all.

On the mig today running spray, the arc sounded right but the wire was balling before transferring. No spatter, but the weldpool was very erratic. I messed about with the settings a little, but basically the machine was set to 30v, induction to zero, gas - argoshield uni (10% co2?), about 12 lpm. Oh aye - 0.8mm wire, cos it was in there. A bit skinny I know...

Speeding up the wire just made it noisy and spattery, slowing down the wire just balled more.

Any ideas why?

Tip?
Eratic wire feed?

What make is it?

I don't like universal TBH for spray....... ermmm torch angle?? stick out???

I think the 0.8 could be an issue tho, carrying that many amps on such small wire, I always think sprays best with 1.2> I take it its solid??

How many IPMs were you putting through the feeder also material size??? parameters are a bit sketchy tonight captin'

Operator malfunction Snowy?

Operator malfunction Snowy?

OY! Cheeky!


Ok, so 0.8 is asking for it. Yes it was solid. Stickout, well I varied it, eh? IPM's, varied again (see first post).

Re paul's question - what make is what, clever clogs? The machine, the wire, the gas, the torch, or the hat on me head?

(NBC 300, Oerlikon, BOC, Binzel, Kromer, in that order)

Oh, and snowy, I don't see how material size makes a jot of difference to a blobby wire, and how you can accuse me of "sketchy parameters" with all that info beggars belief!

Me, I think it was the skinny wire. I'm with you Snowers. I'm sure Paul will be able to offer up some sort of helpful suggestion, given time....

BTW, Alright lads! Can't believe Wozzaaah's left us and joined the dark side!

See - that's why you will never make a mod!

Sorted it. It's yer hat. Was it a suitably loud pattern? That could be your problem.

defo always, what you need is a man who can set up the machine....... ermmmm Matt78 maybe

OY! Cheeky!

lots of stick out, and lead angle may help, I was running at 700IPM on 1.0mm solid tday..... thats with crappy agrosheild goodfornothing........

I find too much heat on smaller sections just makes the weld pool dilute with the parent too much, nasty.......

hmmm yep since when has 0.8m been made for spray at 30V, I reckon some 1.0m in there and problem solved, Oh and put a bottle of heavy on........

Wozz prefect hey, I think hes proved his responsible side, whilst the rest of us have proved ermmm nothing........ It feels like hes flow the nest

Iv got a new one with a US patten on it, not as good as the poka dots one.....maybe its too tight and restricting the blood flow???
