Did you switch the LN 25 to CC??? There is a switch inside the feeder. I
am guessing your Powcon is a stick machine? ( CC??)
Also start out with a relatively low amperage setting.
Is there a graph inside your feeder that gives you some guidlines?
Guys, I need some advice and help... I came across a used LN25 CV/CC
wirefeeder recently, and hooked it all up today just to see if the feeder
worked. Ran the heavy input lead to the back of my POWCON and plugged it
into the (+) receptacle, with the ground lead going to the work. Hooked up
the gas (CO2), turned it on, installed the torch, made sure I had wire,
grounded the LN25 work lead to the work, and turned on the POWCON.
Immediately, Herr Powcon sounded different - it usually makes a click, click
clicking noise at a pretty slow speed while it's idling, but it was really
fast.... not super fast, but faster than normal. I then tried the wire feed
using the incher... it worked fine. Then I saw the LN25 voltmeter - it was
pegged. It pegs at 40 v, and my Powcon runs an open circuit voltage of
around 65-78... way higher than the LN25 appears to like.
I shut the Powcon down. Doesn't look like I damaged it at all, but something
The LN25 manual states that it can be used with any DC welding power source.
It also says that a constant voltage power source is recommended; however,
the LN25 can also be used with constant current (which I'm pretty sure a
POWCON is, right?) power source as long as the open circuit voltage is less
than 110v DC, which my POWCON is. So what might be wrong? I don't think the
LN25's voltmeter should be pegged out, right?
Now, it does say that you shouldn't use the LN-25 models with internal
contactors (mine has one) with non-Lincoln TIG or Square Wave welding power
sources, because damage to the LN25 can result due to the high output
inductance typically associated with these power sources. It also says that
TIG power should never be applied to the LN25. Is a POWCON a square-wave
welding power source? It's DC... I don't believe it's a square-wave
Can someone tell me if this will work, and if so, how do I set it up so the
POWCON and the LN25 like each other?
