Foot brake make it convenient drive when you are driving .By the same way, when we operate welding with two hands,Foot pedal control current is also very convenient.

Keep wire in a clean, dry place when not welding, Rusty wire will not help us now... will it?.

Use gas lens style collet bodies and cups to weld stainless steel. The screen in the gas lens allows far better gas coverage of your welds.

Tungsten size should be selected mainly according to amperage AND polarity and not always dependent upon metal thickness.

Advancements in multiprocess machines are making it even easier to gain quality results for various welding processes...

On transformer tig welders, forgetting to set high frequency to continuous when tig welding aluminum …..

Remote amperage controls Which is better? a foot pedal or hand control?

" sideways scratches on your tungsten will also cause pandemonium and the end of the world as we know it."

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.
