Some welders have a resistor that is obvious and accessible but to give an error code it is likely something else inside. You'll have to look at the circuit board for a component that is burned. If you are lucky you will find a fuse.

Miller welder 330a/bp it will not weld in D/C straight or reverse no ark but will work in A/C its like there is very low volts I was welding and then could not strike a ark


It's likely that your pedal is the problem. Pull the cover and check it electrically - these have been problematic in the past. You can further troubleshoot by selecting constant output and test the output.

I have a help 12 code on my little dynasty machine, and no manual to tell me what it means, is this a major problem with my machine


On this page enter your serial number and you will be able to download your manual http://www.millerwelds.com/service/ownersmanuals.php In the Dynasty 350 manual I see no "Help 12", there is a 32 and 22. If the Help 12 is only displayed when you push a button, it is saying the combination you have selected is not valid.

Hi, starts to weld fine after a few seconds hi


It sounds like you need to change out your SCR chip on your motherboard; Miller makes one that i have installed on all our 350xl's, I don't have the number on hand but i can get it for you tomorrow.

I have a miller dynasty inverter tig welder   It has a help code that comes on when I turn it on the code is p-2


From the user manual for a generic dynasty model welder:
2 Help 2 Display
Indicates an open in the thermal protection
circuitry located on the left side of the unit.
Contact a Factory Authorized Service
Agent if this display is shown.

So you could have anything from a broken or disconnected wire to a bad thermal switch.

You can get user manuals specific to your welder at www.millerwelds.com
