įor brand new clean aluminum diamond plate, set the ac balance to where you have around 67-75 percent dcen.īut some brands of tig welders have their AC balance knob where the higher number setting indicaties more cleaning so if you set the AC balance knob high and your tip of your electrode melts, try a much lower setting. Rule of thumb: for nasty aluminum like a boat prop that has some corrosion, adjust the ac balcne to where you use more dcep. With Old school machines, you get what you get and roughly 55 /45 dcep/dcen due to something called rectification (ouch that sounds painful)…and you don’t always need all that cleaning action that you get from the dcep side.īut with most modern tig inverters, you can adjust the ac balance to more than 90 % dcen. A/C balance-Alternating current contains both electrode positive and electrode negative changing rapidly back and forth.Rule of thumb here is lower frequency for thicker aluminum and higher frequency settings for thinner aluminum.but there are always exceptions. or when you need to weld near threads and you don’t want to arc off and damage the theads. That’s why the transformer is so small light compared to an old tig welder…the A/C frequency knob allows you to weld with a much higher frequency.(HZ)Ī higher HZ frequency setting stiffens and focuses the tig welding arc.pinpoints the heat more.and sometimes that’s a very good thing…like when you need to put one drop of filler metal on a pit in an aluminum injection mold. An inverter steps the frequency of the incoming AC power up before it even converts it to DC. A/C frequency-power from the power company is roughly 60hz in the USA and 50 hz in some countries.Some of the settings that you need to really get a handle on are: So let’s talk about the main tig welding inverter settings. With inverter technology, we can have a 300 amp machine that canĮasily be carried by one person or wheeled around the shop on a lightĪnd the really great thing about tig inverters is that the arc can be tweaked to your liking.īut only if you understand what all those freakin knobs are for. No matter how sweet it welds, or how sweet the deal is, if youĪre cramped for space, dont have adequate power service for a 100 ampīreaker, and don’t have room for a refrigerator sized welder in your Refrigerator and weighs almost 900 pounds. Those old things areĬadillac tig welders but the problem is the darn thing is as big as a I have a friend who just had an opportunity to buy a big “old asīalls” Miller 330 ABP for about 500 bucks. TIG Welder inverters have a bunch of settings and if you don’t understand what they do, you will never get the most out of your inverter tig welding machine.
