Determining 330 a/bp Stick Settings
I decided I'd spend some stick time working with my 330 a/bp figuring how to configure amperage and other settings.
My curiosity right now is only in the context of the Weld Amperage Adjustment Control (WAAC) and the Range Switch.
I was going to use different settings to make up a little chart to help remember settings I used for later reference. What I found is that it's actually pretty complicated because just by changing rod size and type the amperage of the weld changes but the settings do not. And by mathematical formula the percentage of the range on the Range Switch as determined by the settings on the WAAC is not that accurate. Add in the amperage output variation brought about by rod type/size and its gets too complicated (for me) to make up any kind of value chart.
My machine has meters on top so I can video record what the amperage is when arcing.
When I used the setting below of 50 (50%) on the machine dial I got a metered output of 80-90 amps but by formula I should have gotten ~115. Any other settings above that I tried (60/70/80%) report metered outputs lower than expected by formula. So either the dial is not accurate or my math is messed up (heck, or both
). Also, the meter could be off. This machine is old, but in excellent condition.
If any of you have a lot of experience with this machine I'd love to hear how you treated this experiment in your day to day work. How did you determine what settings to use? I'm willing to bet users just found what seemed to work best; do what they needed to and moved on. This particular machine was used by a tig welder and it appears that he only welded with one setting because I had to do some clean up on contacts to clear oxidation to get it working on other settings than the one it was on when I bought the machine. For that welder's purposes (one setting that worked for life) there would be no need to know what different outputs were available.
Anyone ever see a chart for setting variations for this machine? There isn't anything like that in the manual or anywhere I can find.
Yes this kind of complicated things but it was fun to play with, plus I'm retired and needed something to do.
