- Special saving circuit that, if the generator is not used within 30 s from ignition, disables all function and reduces power
consumption to only 25 W (no greater than a light bulb’s), thus eliminating any undue internal heating, increasing generator life
and, more important, saving 1 kWh every four hours of operation. Of course, as soon as the generator starts a welding phase
the device automatically re-enables all the generator functions preventing any inconvenience.
TIG Process
- Very low-noise, fully electronic, solid-state high frequency igniter (no spark points as found in older igniters).
- Safety device which switches off the igniter and resets the cycle if an arc is not ignited within about fifteen seconds.
WARNING: Do not use commercial igniters!!
After welding, do not forget to switch off the welding machine off and shut the gas cylinder valve.
4.3.1 ELECTRODE PREPARATION
It is necessary to use special attention when preparing the electrode tip grinding it so as to obtain vertical makings as shown in
figure (see in schemas section):
CAUTION: HOT FLYING METAL PARTICLES can injure personnel, start fires and damages equipment.
TUNGSTEN CONTAMINATION can lower weld quality.
Shape tungsten electrode tip only on grinder with proper guards in a safe location wearing proper face, hand and body
protection.
Shape tungsten electrode tip on a fine grit, hard abrasive wheel used only for tungsten shaping.
Grind the end of the tungsten electrode to a taper for a length of 1.5 to 2 electrode diameters.
