AC/DC Decisions

[Tom Orrow L]

Called them this morning, still awaiting a phone call back from them.

Jonathan is occasionally meetings but he's usually pretty good at following stuff like this up, i'm sure he'll call.

If you pre set it with the pedal unplugged then plug it back in what do you get. Ignore the display. What does it put out.

you still get 80 amps. Providing the knob has not moved.

The knob does not rotate 360 degrees, it has 2 stops, to mark min and max. so providing the knob has not moved, you will still see 80 amps.

Jonathan says -
'when using a foot control you are putting the machine into manual control and doing everything yourself with regard to start current end current etc the only option is to limit the maximum current with the trimmer on the side of the foot control. Setting this is proportional so min to max is 10-200A some half way will limit to 100A etc thats the only way you can set it off line.'

 

[Richard.]

Well then it's simple. It works just fine.
You unplug the pedal. You set your max amps on the screen. You plug the pedal back in (knowing) your max amps because you set them your self on the screen. You then have the option if you so wish to trim it on the pedal and yes you won't know what you trim it to but if you want to know simply un plug it and pre set the machine again. The pot on the side doesn't set your max amps it's just a light trim and I'd just leave it at max and pre set on the machine whilst its unplugged. This way it works identical to mine and I don't have a problem with it. I'm certainly not striking it up to adjust it.

But still no mention of having to press the pedal in order to see the display to set this amperage. All appears very backwards.

Does this new "Pro" Pedal allow me to control amperage from the panel with the pedal plugged in?

I switch between work loads alot, having to physically keep picking up the pedal to change this is going to become tedious.

 

[Richard.]

You don't need to press it to see it giz. You UNPLUG it.
Then change your setting on the machine. Ignore the pot on the pedal just leave it at max and change your settings on the machine.

 

[Tom Orrow L]

Think it is just a case of unplugging it mate, i don't think its possible to control the amperage form the panel with the pedal plugged in.

 

[Gizmo.Y]

I get that Richard, and have tried that as previously stated.

Set Machine to 80 Amps, Set pedal (Unplugged) to Maximum, Plug in machine, go to weld, certainly not 80 amps, welding certainly towards 200 amps

When plugging the pedal in, this over rides the setting on the panel when the pedal is plugged in.

Are you sure? This is a different problem then. Can you look at the display and see it reading 200 amps.

 

[Richard.]

I want to play with one now to see for myself cos it's bugging me.

 

[Gizmo.Y]

You set the pedal to 80 amps, you get 80 amps to the floor, you set to 200 amps, you get 200 amps, to the floor.

You set Panel to 80 amps, and pedal to MAX, you get 200 amps...

Richard , on the Lorch HT with SSC pedal you can change amps via the control noob on the machine and that setting is what the pedal gives you....never have to unplug the pedal to change the Amps, you just dial in the max you want on the front control panel and that's the max you get from the pedal.

 

[Richard.]

Back to square 1 then. Thanks for clearing that up. So it's not like mine then. The pedal pot completely overrides the panel settings. I wonder if the second pedal pot was bypassed and not used would it then start using the settings generated from the machine??

Yes I know mate but mine is overridden by the victor(isum). Although lorch built the machine it's adapted by victor to take there 7 pin plug and like the thermal arc machines it's got there software in it to make it behave like this when it recognises a remote. Mines a tweco arc master 220. (Black lorch)

 

[Gizmo.Y]

thats the ONLY gripe i have with the machine, is the fact the pedal over rides the machine. I'd rather set my amperage up via the front panel, which is at a nice height when im sitting down (hence the new fancy Trolley i made)

The fact you have to press the pedal, activating HF and Gas flow, to set the amperage on the pedal knob. just seems backwards and wrong.

I'd rather have a pedal with no Amperage knob on it at all. I want to control it ALL via the display panel.

 

[Xup]

If Giz's issue cant be sorted with a pedal without the pedals own control knob I'd be very surprised, this machine has a very good rep can't see it having such a good rep if it only works as Giz's is working above if used with a normal pedal ?.

Ok. What about this then. Open up your pedal and have a look at the main pot. Get the value off it. 5k,10k etc. Then do the same with your old pedal off the eastward. If they are the same you could then doctor the Eastwood pedal to work with the parweld and see if it works as you want it too.

 

[Gizmo.Y]

To be fair richard....I prefer the parwelds pedal to the eastwood...Ive grown to like it in such a short space of time (Not sure if you remember my eastwood pedal, not the best).

As above, if a pedal without the control will solve my problem...Then link me to a pedal so i can make the purchase! Unless Parweld will take this one back in for an exchange...

 

[Xup]

There must be someone on here using the same machine with a "normal" pedal who can chime in to say how it works with the normal pedal ?.

 

[Richard.]

Take the pot away then Giz. Easy peasy
You'll have 3 wires going to your side pot. Take them directly to the main pot. Job done.
