1)
Inductance - Make the arc soft or hard.
2) Gas pre-flow - Supplies a quantity of extra gas, for a
given time set in the factory, before starting to weld (from 0 to
3 seconds with a 0.1 seconds interval for adjustment);
3) Run in speed - Adjusts the starting speed of wire to the
piece. The given value is a variation against the values set
in the factory (from 0 to 10 with a 1 interval for adjustment);
4)
Hot start - over current when ignition
5)
Start current - in special 4T mode. The current of start
stage.
6)
Start voltage - in special 4T mode. The voltage of start
stage.
7)
End current - in 4T or special 4T. The current of end
stage.
8)
End voltage - in 4T or special 4T. The voltage of end
stage.
9) Burn back - Adjusts the length of the wire coming out of
the gas nozzle after welding. The given value is a variation
against the values set in the factory. A higher number corre-
sponds to greater wire burn back (from 0 to 10 with a 1 interval
for adjustment);
10) Gas post-flow - Supplies a quantity of extra gas, for a
given time set in the factory, before finishing welding (from 0
to 6 seconds with a 0.1 seconds interval for adjustment);
11) Spot time - Time needed for spot-welding (after press-
ing the torch key) after which the arc automatically switches
off (from 0.1 to 20 seconds with a 0.1 seconds interval for ad-
justment).
12) Dual frequency - Establishes the dual impulse fre-
quency (from 0 to 5 Hz with a 0.1 Hz interval for adjustment);
13)
Dual dynamic - the dual pulse peak and base current
adjust. The percentage is -20% ~ 20%.
Table 5
sums up the special programs available in the var-
ious welding modes and processes.
Create and memorize new GMAW welding
spots
Figure 18
Establishing a new welding spot as follows:
• Press the MEM key then enter the memory options
page;
• Select the "Save" option and press the ENCODER key
then enter the memory channel page;
• Select the channel in that the data will be saved and press
the ENCODER key.
NOTE: The creation of a GMAW welding point implies the
memorization of all the corresponding special functions.
Call up GMAW spots memorized beforehand
Call up a welding spot as follows:
• Press the MEM key then enter the memory options
page;
• Select the "Load" option and press the ENCODER key
then enter the memory channel page;
• Select the channel in that the data were saved and
press the ENCODER key.
