Arc starting issue Everlast 210 ext

[ToTu]

Or if this machine have point what i can fix or adjust, i can not find it. :-)

First thing I would try is to clean that board with circuit cleaner. Because there is high voltage present, if any of that dust on there is carbon, there could be voltage tracking going on and leaking your HF to ground through the dust.

Nah,

It's obviously gapless. And I see it does have a tiny LED.

Otherwise, below is a thread link that talks about how that model has a lot of adjustability in the HF arc starts, regarding duration, frequency, and amps.

I don't know what the procedure for involking those codes and hidden menu is, but I'm sure it's something simple, like holding down two knobs at the same time for 5 seconds, or something like that. It doesn't mention the procedure. Maybe you have the manual which does say how to do it, though. Or, someone on the forum may know.

So, that's what I'd do first; maybe increase the HF time a bit, try changing the HF Hz a bit, and maybe maybe increase the start amps a little (on my 2015 model that is a setting on the panel itself).

Please let us all know how it goes and if there's any improvement. Otherwise, maybe Mark, with Everlast, knows if those daughterboards are still available and what it might take to get one moving in your direction.

In the second menu,have 10 channels
D01: Vacant
D02 ：High voltage stricking ARC time :0.5-2S
D03: High voltage stricking ARC frequency :10-100HZ
D04: DC High voltage stricking ARC current :10-100A
D05 :AC high voltage stricking ARC current :15A-100A
D06: Vacant
D07: AC DC LIFT starting ARC current :10A-100A
D08: For Adjust the fingertip AMP control TORCH."00" --4T power off ;"01"-- 4T is on
D09:For adjut the VRD ."00":VRD is ON ;"01"VRD is OFF
D10: For the AC Pulse selection. "00" means single Pulse ,only AC ;"01" means double Pulse .

I examined little bit more..
I found loose solders from the litle board, I soldered them again and I removed all the dust and metal out and sprayed the new lacquer on the surface . It didnt work. I know where is the hidden menu and i have try to adjust from there and it wont do anything.
I also noticed today when i was testin on ac that it wont get arc if i scrach a workpiece(i will get small arc and it will die after 1-3 sec), i have to do that three or four times and then i will get arc. On dc this wont hapend.
I also changed the ground cable.

If you are having issues with that unit, there's not much to do except replace the whole board.

The machine has been very little use, it has been unused for months and then I may have weld a little bit. the machine is at my home and i do not use it at work. I have cleaned the machine several times by taking the side panels off and cleaned it by blowing compressed air. I have also keep the machine on the wall(on the shelf) so that vibrations and shocks on the table will not be transmitted to the machine.

I will continue investigation tomorrow.

Nothing short of a new board will fix it. We've been there done that with that model...main reason we switched production.

[ToTu]

Did you Mark mean only the small board? Or also the main board. I asked today from finish everlast suplier do they have the board to me. Now i am waiting their answer.

For fun i calculated how much i have used the machine .
I know how much i have used argon it is about (if i remember right ) 5,5 x 8000m3 = 44000L off gas.
My argon flow is 8L/min so 44000L / 8L= 5500min and i divided that by 60 min, 5500min / 60min= 91.66h
Not much.. 91.66 hours of use. This is approx of use.

Then i can calculate also the cost off one hour. The machine cost ~1600 Euros if i remember right.
So 1600e/ 91.66h = 17.45e not so much for one hour....

But if i calculate also like this.
If i would use it at work and it would last, maybe 300 days in a year and i will use it on a one day lets say.. 5 hours. 300days x 5h= 1500 Hours
So 1600e /1500Hours = 1.06 Euros for one hour
And if the machine would last 2 years the cost would be half of that.

I like to calculate things...
