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.

When it comes to plasma cutter start functions, you always get two answer:

Set the machine so that you are at welding amperage with the foot pedal depressed about 3/4 of the way.

Put a vent hole in anything you weld that will be sealed up completely or air will heat up and expand and blow away your shielding gas or even blow out at the end of the weld bead.

New technologies offer optimized stick and TIG performance, designed to specifically meet the needs of open root pipe welding.

The more vertical the torch is, the more arc is directed into the part. Think about it like this…

If you are welding stainless pipe with a purge and your weld is still sugaring, remember argon is heavier than air and flows like water.

Well there is always a bit of fudge factor because flowmeters are different, and machines are different …

Usually AC is better for these situations. also, if you have large gaps to fill AC is usually better.

Because helium carries so much more energy and heat than argon, aluminum can be puddled very quickly so a puddle can be made very quickly even on very thick aluminum.

First of all, not every tig weld machine can weld aluminum. Its one of those things that really sets a welder apart

High quality cutting performance.
Accessories:Trafimet CB-50 torch

Our mastertig-200/250ac has the full functions of tig welding.
DC tig is used for mild steel, stainless steel, copper, titanium and nickel alloy.
AC tig is typically used for welding aluminum and similar alloy.
MIX tig is used for welding two different thickness of work piece.

It is a lightweight and compact designed dc tig welding machine, including a 250amps power source as same as our Protig-250Di.
