Mig Tig Welder

An overview of TIG welder Settings   by Oleg Gladshteyn

There is a general misconception that welding is quite simple to learn. It is nothing but joining two or more metal pieces with the help of a molten solution that forms the necessary bond between them after solidification upon cooling. Theoretically speaking, it is nothing more than that. But there is more to welding that you ought to know if you wish to become a professional welder. Welding is no joke by any means as there are lot complications associated with it. Which metal pieces are to be joined together? What’s nature of those metals? Which procedure or welder to use to weld them? What settings to imply in order to get a proper yield?

Welding as such is an art that requires tremendous amount of focus and concentration on your part. The slightest mistake is more than enough to spoil the quality of your weld or the quality of your end product. And if such a product goes into manufacturing and then deployment, depending upon the end product that used the welded portion, it could lead to several other possible disastrous consequences. Say for example, medical systems that makes use of welded spare parts. If such a system fails or explodes while it’s functioning, it could turn out to be quite disastrous. Thus it is very important, that you understand the intricacies and imperative requirements when it comes producing quality welds. On this note it is very important that you set the systems, gadgets and other resources employed while welding appropriately irrespective of whether you are using a MIG welder or a TIG welder.

Let us take a look into the TIG welding Inverter Settings for a brief understanding.

i) Amperage: Reading of the Amps supplied from time to time.
ii) Alternating Current Frequency: The inverter regulates the incoming power frequency before converting it into DC. The same knob allows you to handle much higher frequencies. It increases the focus of your welding arc as well which is critical and imperative at times.
iii) A/C Balance: A/C contains both positive as well as negative electrodes that changes dynamically from time to time. TIG inverters give you the flexibility to adjust this input balance depending upon what you are welding.
iv) 2T: TIG inverters bypass the 2T and 4T settings as the amperage control overrides up-slope and down-slope stuff. 2T gives you a flexible option that converts the torch switch into a 2 position switch. You get an arc when you press this switch and it terminates when you don’t.
v) 4T: 4T setting is used in conjunction with up-slope and down-slope settings. In this setting, upon pressing the switch an arc is created. Letting go of the switch, arc up-slopes to main amperage value setting. Proceed with welding. Press the button, arc down-slopes to lower amperage, letting go of the switch, the arc terminates.
vi) Pre Flow: Total time of gas flow between the time you press the switch and the arc is generated is projected by Pre Flow.
vii) Post Flow: Total time of gas flow after the arc terminates is projected by Post Flow.
viii) Up-Slope: Steps up the current to whatever levels or rates you set from start amperage to operating main amperage.
ix) Down-Slope: Steps down the current to whatever levels you set.
x) Start Amps: Low amperage startup
xi) End Amps: Estimates final amperage before arc quits.
xii) Pulse Frequency: Pulse generated per second. Higher pulse rates help to focus the arc more efficiently.
xiii) Peak Pulse Percentage: Gives you more control over pulse generated allowing you to limit heat input or agitate puddle.
xiv) Pulse Width: Duration of high pulse amperage that stays on.
