Machine setup for TIG welding
1)Connect the torch to the - connection and the gas hose to the gas
outlet.
2) Connect the trigger control plug on the torch to the trigger socket.
3) Connect the Earth lead to the + connection.
1- Pre gas flow time adjustable from 0-1.0s
2- Start current (arc starting current while trigger is held down in 4T
mode) 5-200A
3- Slope up time after trigger is released in 4T mode at the start of
the weld. 0-5.0s
4-Welding current, main welding current in 2T or 4T mode
5- Pulse function can be toggled on or of by pressing the button
6-Pulse background current (only available if the pulse function is
switched on.)
7- Pulse frequency (only available if the pulse function is switched
on.) use low frequency for improved arc control and heat input. Use
high frequency for narrower arc and increased penetration.
8) Pulse duration % of pulse frequency
9) Downslope time when the trigger is released (2T) or repressed
(4T) 0-5.0s
10) Final current is maintained after the downslope time in 4T mode
until the trigger is released.
11) Post gas flow. 3.0-10.0s
7.0 Fault Finding
MMA welding problem
Description Possible cause Remedy
Gas pockets or voids
in weld metal (porosity)
(a) Electrodes are damp
(b) Welding current is
too high.
(c) Surface impurities
such as oil, grease,
paint, etc
(a) Dry
electrodes
before use
(b) Reduce
welding
current
(c) Clean
joint before
welding
4) Rotate the selector knob A to position 1 or 2. “T means you have
to hold down the tigger all the time 4T means the trigger can be
released during welding mode to 2T or 4T . (Note in 4T position you
must press and release to start the process and press and release
again to stop the process. When stopping in 4T mode holding down
the trigger button will activate the slope down, releasing the button
will switch off the arc)
5) Us the main control knob B (rotate and press) to select the
different welding parameters. As detailed below
