Need a little help with my new machine

[dennis]

I got my replacement multipro 205 today. Put my plug on and at first it looked good. I hooked up the air and tried to cut some sheet metal. I got noise and everything like its working but it didn't work. I cranked it up to 40 and tried again with nothing. I got power, air, and flame but no cut. Consumables are new and tight. I measure a full 220v going in. Even cranked up all the way it will not cut 16g sheet metal. I'm sure I must have overlooked something. Any advise? I'm on 14 hour days and no time to call in.

How is the ground clamp??

[dennis]

ground is good and metal is ground.

You are not getting arc transfer OR you have the torch in the + connector.

There may be an issue with the markings on the latest batch of MultiPro machines.

I had a call today from a guy that was having a similar issue with the plasma torch, and it seems the connectors are marked in reverse. “Workclamp”is actually the – connector and “Torch” connector is the +.



I was about to send an email to the factory about it. but we need to verify that the Torch connector is actualy the negitive port on this machine.

My torch is in the neg side as I was told to do even though the machine is marked with the torch being pos. I get no transfer. Kinda like it is not making enough power to actually work. consumables are new and tight.

UMMMM.... Ray, if the face is actually marked correct and I'm using it wrong will it hurt my unit? I was going to try again before work but your reply got me thinking it might be a bad idea. At this point I have tried using it less than 2 minutes and have no warning lights.

[dennis]

I guess the best thing to do now is miss work and call in so I can return this thing for a refund and buy something that works.

[dennis]

Ok... It works. Instructions were backwards. My face plate was marked right. Max cut is 1/2 inch, will not hack 3/4. Gonna play around with the air a little later and see if that helps. First machine died in under a couple minutes. At this point I'm at about 6 minutes of cutting with good results 1/2 inch or less. Customer service is very good.

[Ray]

Still not clear on what was incorrect? The manual? Or themarkings on the welder.

Does the manual say to connect to the positive port.

I was under the understanding the connectors were markedTorch and workpiece.

I’d like to know so I can direct other correctly, I haven’tseen one of the special units yet.

The manual was wrong and the face plate was right. It works now. A little bit shy of the specs for power. I'll need to adapt a torch that fits me better. I just ran a few sticks of 1/16" 6013 and it did good. I cut all the parts for my new welding cart and it done real good.
