Mild Steel TIG Welding Settings

Scroll down for Simple Settings

There are a lot of knobs and settings on newer tig welding machines.

But when it comes to mild steel tig welding settings,

Fortunately, most of them can be set once and ignored

It starts with making sure the TIG torch is plugged into the correct port.

This will almost always be the negative plug and will usually have a small TIG torch icon label.

Read the manual for your machine to be sure.

Typical mild steel tig welding settings will be as follows on most machines.

DC Electrode Negative (DCEN)
Pulser off
pre flow set to .5 seconds
post flow set to 7-10 seconds
3/32" tungsten (2% lanthanated, thoriated, ceriated, or E3 will all do fine)
#7 cup with 14-21 CFH argon flow
Amperage set to one amp per thousandths of metal thickness (up to .125")

Top 3 tips for TIG welding Mild Steel

aim for an arc length that is equal to or slightly less than electrode diameter (arc length is distance from tip of tungsten to puddle)
limit torch angle to around 15 degrees ( torch angle can be very forgiving provided you hold a tight arc)
Keep the hot tip of filler rod shielded in the argon plume and snip off the tip for restarts if tip has is discolored... or not kept shielded in argon
