The best welding effect - 'FISH-SCALE'

'Fish-scale' is a technique of welding, known as its cataphracted weld joint. It's regarded as the best welding technique of the world.

It's a TIG welding method that through swing of wrist make welding nozzle rolling as the scalloped shape during welding process, it's also known as 'swing welding'.

Method of handling rod

TIG welidng is open arc operation, which can observe the shape andflow of weld pool very clearly. The key is to keep your hand very stable and steady in welding!     

Control method: Use the index finger that holding torch to support the welding plate. The length of tungsten electrode could be choose as per the depth of crevasse, usually is 3 - 5mm.

Method of handling wire

The method of handling wire should be choose as per the size of crevasse. When the size is small, welding wire could place at the middle of welding pool and continously 'feed-in'; When the size is big, could feed the wire at two sides bit by bit, and the torch should move aroud to make sure the edge fuse well.

Welding tips

To evaluate an beautiful fish-scale welding effect, the excess weld metal of TIG welding bead should be 0 - 2mm, and the surface should be smooth. The angle, and welding current are quite important! The width and thickness should keep the same when rod moved backward, usually we make it moved upward as 'V' shape in vertical welding.

Plus the current is last but not least, the rod is easy to stick with plate when the current is too small; yet the plate will be punchthrough when surrent is too big. Hence current is always a hot potato to greenhands or freshmen. How to deal with it when we are unskilled? JSKWED make you weld easy and easy, to press 3 seconds into our 'simple mode'.

SIMPLE MODE: TO PRESS THE MAIN CONTORL KNOT 3 CECONDS, THE MACHINE WILL ADJUST ALL PARAMETER INTO A PROPER SITUATION, WHICH CAN LET YOU WELD ALUMINUM NORMALL, EVEN IF ALL PARAMETERS ARE MESSED UP BEFORE.
