In simple terms, pulsed MIG is a non-contact transfer method between the electrode and the weld puddle. This means that at no time does the electrode ever touch the puddle.

If you are left “scratching” your head about the differences in the different start methods of TIG, you are not alone. Many experienced users get the facts wrong when it comes to the 3 basic ways you can start a TIG arc.

The gas metal arc welding (GMAW) process uses four basic modes to transfer metal from the electrode to the workpiece. Each mode of transfer depends on the welding process, the welding power supply, and the consumable, and each has its own distinct characteristics and applications.

The Pulsed TIG function switches the amperage from a high(peak) to a low(background) at a set rate(PPS). Pulsing can reduce heat input by lowering the average amperage, increasing control of the weld puddle, penetration and distortion. The following parameters can be adjusted for desired results:

TIG welding filler wire and Mig welding wire from a spool are essentially the same composition except that mig welding wire often contains more silicon and that can actually be a good thing for TIG welding steel.

Use stainless steel wires for stainless steel, aluminum wires for aluminum, and steel wires for steel and nickel alloy rods for nickel alloys. (cast iron is welded with nickel wire but that’s a story for another day)

If you have problems feeling the wire with a glove, Try some mechanics gloves or really soft and thin tig gloves like Topwell BL-1005 skin tig gloves or even some woven cotton gloves...

TIG welding is not nearly as forgiving as Mig or stick when it comes to dirty metal. For TIG welding, the metal needs to be clean; no rust, scale, paint, etc.

Shielding gasses for TIG welding Argon is not the only shielding gas used for TIG welding…

With the continuous progress of science and technology,Most industrial mechanization industry also tends to one-button operation.For example, the welding industry.

Ideally, torch angle should only be around 10 degrees or less. Too much torch angle will deflect the heat and melt the rod before you ever get it into the puddle.

Don’t use too much torch gas when welding aluminum on AC. Aluminum takes a lot of amperage to weld.

Extend the tungsten out of cup 1/4” to 5/16” when welding high amperage aluminum or heat will radiate from the cup to tungsten and reduce output, especially if the orifice is too small.
