wire speed traking

[cymax]

no just volt meter
i am welding 3/16

what i do is
i set up the voltage first then incrace the wire speed until i reach my desired arc voltage
sp from the volt amp chart in the user manual you see that you get 20 volts and 160 amp at setting 7 on the voltage pot...

OK this is for all of you that have problems with the wire speed tracking
i think i have found the solution

i made a couple of beds today with .030 wire and co2 i decided to use to volt amp chart of the mm175 and it gave me good results

so dan if you can give it...

dan i don't know ask the tech rep at miller
i have to call my welding supply store to see if they can lend me a c25 botle for a couple of days to give it a try

i wondre by how much does the wire speed slow down when you have the voltage pot set at 5 for example ?

hello andy
no i will not give you my serial number of my machine i think that day someput something in my coffe .
i just talked to a tech rep at miller
he told me that insted of changing the voltage i should change only the wire speed
this is somewhat confusing now...

[cymax]

i see
well i would need the schematics to see
or design a completely know board that would be an option

there is a dude i don't remember the web site
he made the circuit board for his homemade mig it was designed for a 115 volt i wonder if it would work for a 230...

BTW dan if you have msn email me and i can add you to my list

[cymax]

dan,
yes i have read some of your previous posts

in regards to the the removal of the wire tracking i read on the the hobart post that when at 10 the wire motor receives ~20volts
the trick would be to directly route the 20volt from pot to the motor
this would have...

Dan
i know what you are talking about when comparing the 2 machines ei mm175 mm210
i had a chance to run the mm210 and give it a test drive it's a reall good machine .
i don't like being told what to do with my mm175 and this is basically what is happening

i use...

my issue is not with the welder it self it's with this added technologie.

here is a quick example
welding 1/8 mild steel using .030 wire you would get 2* 125=250 ipm

now on the welding i would se 250 ipm at about 35%-40% now how do you set up the voltage...

ok here it is the question

What does wire speed traking do
from what i understand as i increace the voltage the speed of the wire increaces.

i would like to know if there is any way of disabeling this feature on my mm175
i was tought old school and now i am...

[cymax]

i see
so in my case using co2 and .035 s6 wire
do you think i should leave a root or should the machine go right trough

[cymax]

thx guys this really help
i figured out y i did not have any penetration
when welding 3/16 i did not leave a small root opening
so the pudle did not have any place to go but build up
i left a small root opening about 1/16 and it made a differance

i read...

[cymax]

yes you did thx

i was doing some destructive testing and it seams that when i bend the plates
root bend the weld give it seams when i take a look it looks like there whas very litle penetration the type of joint was sa simple but weld with not prep done
i did not leave...

[cymax]

Hawk i think i asked my question wrong and did not give enough info

firs i am welding mild steel .188
i have read that for a but weld you need to prepare the joint with a V if you material is over 1/8 thick

second
the system that i use posted in my last...

[cymax]

hello

i currently own a miller 180 mig welder
i use strait co2 as gaz and .035 s6 wire

my question is
when i use the setting recommended by miller the seam to be a little hot
is that possible

my second question is
is it...
