Well i was at a friends house he was showing me his hobart welder. i noticed it had seven voltage taps, then started thinking how in the heck do i read the voltage on this thing(im assuming each tap is a certain amount of volts ?) The gmaw machines in the factory i worked out all had digital display that read the voltage before you put a work load on it. sorry if its a odd question just never worked with a smaller machine before.
Reply:You just have to read the manual, they have some recommend settings, find some scrap and fine tune it for what you like to do.old Miller spectrum 625 Lincoln SP-135 T, CO2+0.025 wireMiller model 250 and WP-18V torchCraftsman 100amp AC/DC and WP-17V torchCentury 115-004 HF arc stabilizerHome made 4 transformer spot welderHome made alternator welder
Reply:on the inner panel is a guideline like with most i have seen but just tap 2 wfs 30,40, 50 etc etc. I might go look through his manual see if their is any info on the relationship of the tap setting to voltage under workload.
Reply:Why do you "need" to read the voltages. While welding, you're not "reading" the voltage display. You should be watching the puddle wet-out and "listening" to the arc sound. Within a short amount of time, your visual observation of the puddle and wire speed, coupled with the audio tone of the "sizzling bacon" sound will tell you all you need to know wether you're at the "sweet spot" or not.Lincoln Power Mig 216Lincoln AC/DC-225/125Miller 625 X-Treme PlasmaMiller 211 Forney 95FI-A 301HF 91110Victor Journeyman O/PMilwaukee DaytonMakita Baileigh NRA Life Member
Reply:for any given voltage setting you set the wire speed as Superarc noted by the sound. With the wire speed correctly set, you decide if you have enough heat/penetration in a joint or not. If you don't you turn up the voltage to the next tap and readjust to optimal wirespeed. Sometimes if you are blowing through the metal you have to turn it down, and readjust the wire speed. Actual voltage #'s don't matter.Miller Multimatic 255 |
