Snowmobile Tilt Trailer Build welding project – Day 6
1 hour in the shop : setup + welding 5 rear flats + cleanup
Progress no matter how slow is progress.
It is amazing how fast little tasks add up. I’m not feelin it yet on this Snowmobile Tilt Trailer project. I know when projects start rolling it feels amazing, but I’m just not there yet with this build.
Is there some kind of marker when that feeling will show up?? Is it a time thing? Do we feel it after a halfway point in hours put in?? Or maybe effort put in?
I’m slogging through at the moment. Each time I want to work I’m lining up a babysitter, making sure it’s not conflicting with what THEY want to get done in a day. Making sure my son is not only ready and on time but also packed for ANY possible scenario a nine month old could possibly encounter….. Mom life – the struggle is REAL.
Demystifying Simplified Machine Settings
Day 4 of my trailer build I asked the question:
“Is there any way to accurately know the Amperage I’m welding with when my machine has a simplified user interface Amperage dial?”
I asked my Electrician Hubby if there is any way to test or figure out the Amperage on my simplified wire feed machine. He DOES NOT suggest using a Multi Meter to test this because the Constant Voltage power source commonly used for GMAW(MIG) and FCAW(Flux Core) creates a momentary ‘short circuit’ as the circuit is completed (wire touches work) before returning to machine weld settings. It’s because of this huge amperage spike and instantaneous electrical ‘load’ that he doesn’t suggest exposing a Multi Meter to.
The simple answer is actually “No.” There is no accurate way to know the amperage you are GMAW/FCAW welding with. This is because of 2 reasons:
The settings you set on the machine before welding are not ‘under load’ meaning they are set while there is no actual electrical current flowing through the system. On a digital display machine you could have another person look while you are welding to see a number, however this is not useful as far as machine settings also because….
The machine is constantly adjusting itself to compensate (voltage sensing) for the small (or large) changes in ‘tip-to-work’ distance. We are human and we breathe. We have blood pulsing through us and muscles reacting to our senses. The machine needs to compensate for our humanness and therefore can not weld well at one precise setting. The Multi Meter would also just give you the range.
We drew up this simple formula that’s easily applied to other machines.
I know, I hate math too! Hold tight, I promise it’s not too bad…
From the machines’ instruction manual specifications we found the Output Current – 35 -80 A
My Miller 211 welder also has a ‘simplified’ user interface and uses material thickness as the stages for amperage range. It can be calculated in this same way. Remember, the stages on the dial can be designated in ANY WAY – letters, pictures, numbers or material thicknesses – all they are doing is dividing the range. So if we know the range from the machine specifications, we can find a relatable number to the settings we prefer.
BAM! Relatable to real life and transferable to digital machines!!
How awesome is that!?!
Knowing your own personal preferences is so important when using other machines. I know I don’t like the time it takes to get familiar with a new or unknown machine (they ALL seem to have their little differences) If I can cut down that time learning the machine, I’m more confident with my settings and can get to welding faster.
Who doesn’t want help with that??
Hope this helps!
