A. Weld speed is too fast.
B. Weld speed is too slow.
C. Arc is too long.
D. Ideal weld.
A solid weld bead requires that the electrode be moved slowly and steadily
along the weld seam. Moving the electrode rapidly or erratically will prevent
proper fusion or create a lumpy, uneven bead. To prevent ELECTRIC SHOCK,
do not perform any welding while standing, kneeling, or lying directly on the
grounded work.
Finish the bead
As the coating on the outside of the electrode burns off, it forms an envelo-
pe of protective gasses around the weld. This prevents air from reaching the
molten metal and creating an undesirable chemical reaction. The burning
coating, however, forms slag. The slag formation appears
as an accumulation of dirty metal scale on the finished weld. Slag should be
removed by striking the weld with a chipping hammer.
LIFT-TIG
ACCESORY
Tears off the main attaching plug Turn off the power source.The ground cable
connect the positive electrode and screw it tighter.The end of the
ground cable connect the work piece.The torch cable connect the
cathode and screw it clockwise.Tighter the gas tube bolt which connect the
protection gas cylinder.Inserts the main attaching plug.
The touch pilot arc
Warning! Turn on the power source , Welding torch's tungstic electrode al-
ready charged. The tungstic electrode could not touch anything.this series
welding machine TIG weld uses contact striking the arc way:
Striking the arc method following step:
A. Turns on the welding torch built-in air valve
Approaches the striking the arc spot the spray nozzle to cause the tungstic
electrode and the work piece is separated 2~3mm
