LN-25 ? Cruizer ?

[nfinch86]

To weld with the LN-25 my Ranger 8 has to be on High Idle.
Should the Ranger 8, automatically go to high idle when I strike an arc ( pull trigger ) ?

I've not run my Ln-25 off a Ranger. But on my Miller Big-40 D. When I switch from CC to CV it automatically goes to high idle. Also when I connect ground wire from LN-25 to welder ground wire it goes automaticity to high idle. <br />
Another thing I learned from my LWS rep. For the LN-25 to work proper it wants min of 250 amps from welder, then set volts & wire speed. <br />
So I set welder course setting to max then switch to CV mode and adjust volts to desired voltage, adjust wire speed. Then it's hood time. <br />
Hope it helps. Greg

Thanks, But I think it's a different setup.
For example - In either cc or cv set at low idle, if I plug my grinder in and turn it on , the engine revs up to high idle.

I thought it should do the same in cv for the LN-25 , pull the trigger and rev up to high so I can weld.
But - No it will not do that, I have manually hit the switch to high to be able to weld.

Thanks -

No problem. <br />
My LWS rep called me this morning on another issue. <br />
I ask him about Ranger 8 and LN-25. He said should be basically same as Miller engine drive. When you contact ground it should sense need for voltage to run wire feed motor and unit so should kick up idle same as grinder would. <br />
Also he said when switch to CV mode should kick up idle. Problem probably in welder. <br />
Like I said I don't have Ranger 8. So I'm just relaying information. He has always got me going if I had a problem. <br />
Good luck

I really appreciate your help.
I'll have to have a look to see if there's something I can do.
It's really not that big of a deal, as I just have to switch it manually.

Thanks again;

Well, its an either or senario, most people merely leave the machine in high idle, so the arc does'nt have to build up, however. low idle is fine as well, just hit the trigger, engine revs up and off you go.

Now 035 and above is easy, 023 not so much, just not enough oomph

Again, the CC/CV switch on the feeder, has ABSOLUTELY nothing to do with actual CC or CV welding. Because CV has much less voltage , another set of internal caps are charged to drive the feeder wheels

Thanks Cruizer;

I generally run .035" & sometimes .045" hard wire, and it will Not Rev. up by just pulling the trigger.
I have to manually switch to High idle to weld with the LN-25.
It's no big deal, I was just curious " Why " it will not rev. to high idle when I pull the trigger ?

PS. - If the cc/cv switch on the feeder has no function, why is it there ?

As I said that switch is for capacitor charging on low open circuit voltage in CV to drive the feeder wheels. on any other welder, hitting the trigger revs the engine up. Thinking that your low idle is too low. should be around the 44 Hz mark low idle.

OK,
I have it set at 62.5 Hz. in high idle.
So, can I set the low idle as well ?

that one is a little tougher as its not set at the carb, instead set with the positon of the idle solinoid

OK, What do I do to correct the low idle to get the 44Hz. ?

Thanks for All your help ;

Well get a meter that reads frequency, loosen and adjust the solinoid housing to around the 44HZ mark, tighten and trest

I just check it & it reads 37Hz. , Now not being a tech. person, where is the solenoid housing ?
What does it look like ?

The thingy that revs the engine up and down

Will that not also make High Idle increase , taking that higher than the 62.5 Hz. ?
