O que significa TIG Lift Arc?

O que significa TIG Lift Arc?

LIFT ARC – A função possibilita abrir o arco em TIG somente tocando a peça, sem a necessidade de riscar o eletrodo. Caso o tungstênio toque a peça durante a soldagem, a tensão cai para 10 A com o objetivo de preservar o eletrodo e não contaminar a peça.

Como é feita a solda tig?

Soldagem TIG (Tungsten Inert Gas) ou GTAW (Gas-Shielded Tungsten Arc Welding) é um processo que utiliza um eletrodo sólido de tungstênio não consumível. O eletrodo, o arco e a área em volta da poça de fusão da solda são protegidos por uma atmosfera protetora de gás inerte.

Para que serve o gatilho da tocha TIG?

Já numa inversora TIG, o controle do gás é feito diretamente no gatilho da tocha. O equipamento controla a abertura e fechamento do gás através de válvula solenoide, ativada ao apertar ou soltar o gatilho da tocha.

When to use the lift Arc TIG function?

• Lift arc question. The Lift-Arc TIG function is used when you don't want to start the arc by "scratch" start or by using high frequency. The welder will put a small amount of DC voltage at the electrode and when the welder sees this voltage drop to zero (touchin the tungsten to the work piece) it will start ti pre-warm...

Is it OK to use lift Tig in welding?

• It’s important to note that lift TIG is not acceptable for welding procedures that specify a non-contact arc starting method. This may be the case with pressure vessels and process piping or other welding systems that require high frequency arc starts.

What's the difference between MIG and TIG welding?

• Both MIG and TIG processes utilize electrical arcs to produce heat and therefore join metallic material and/or objects. TIG is a newer form of welding, and many remain unfamiliar with it. So how is the lift TIG welder explained? A lift TIG welder is a machine that utilizes the TIG welding process with a lift start to the arc.

How does lift arc ignition work in welding?

• With Lift-Arc Ignition feature, to start the arc the tungsten electode is touched on the job and lifted off. The start-up current is very low and therefore the tungsten barely sticks to the job and the sharpened point is not damaged. The tungsten is then easily lifted off the job.
