250-300 amps for a fillet weld on 1/4" steel? Are you Kidding me?
These
little weld calculators are very useful for newbs because they are a
ready reference for all the TIG welder machine settings like polarity,
high frequency, and other variables that make a big difference in not
only TIG welding, but also MIG and stick welding.
I know a guy
who has little labels stuck all over his Miller Syncrowave 250 TIG
welding machine so that he doesn't have to look it up every time he
needs to weld something. He is a machinist who does some welding. Not a
full time welder . With all the CNC programs he as to think about along
with feed speeds etc., he does not care to memorize TIG welding
settings. A welding calculator would really help him.
Remember these down and dirty tips for setting TIG welders and maybe you wont even need a welding calculator.
1. For Steels, stainless steels, Nickel alloys, titanium etc (everything except aluminum and magnesium)
DCEN,
high frequency on start only, Argon gas flowmeter set on 20 cfh with a
#7 gas lens type nozzle/cup, amperage switch on remote, contactor
switch on remote
2. For Aluminum and Magnesium
A/C,
high frequency set to continuous, argon, or argon/helium mix flowmeter
set to 15 cfh with a #7 cup if machine is equipped with A/C balance,
set it to 7, amperage switch on remote, contactor switch on.
