Spot
welding
① Press the on/off button, strike arc to set
value ②Last spot time, quench arc.
Table 4.1 the operation mode of TIG welding
Note: graphic
means pressing on/off button of the TIG torch,
means loosing the on/off
button of the TIG torch,
means pressing the on/off button once (press, then loose)
Upslope time(SLPU):
0
～
15s The upslope time means the time, which the current from 0 to set current, it
should be set according to the technological requirements
Downslope time(SLPD):
0
～
15s The downslope time means the time, which the current from the set
current to 0, it should be set according to the technological requirements
Arc strike mode(HF):
the welder provide two arc strike modes including lift (HF) arc strike and contact arc
strike.
End current(EndI)
:0
～
200%, it means the percent of the set current, it is used for filling the crater.
Initial current(HotI):
0
～
200%, it means the percent of the set current. The initial current is the current
after arc ignition; it should be set according to the technological requirements. The higher initial current,
the easier arc striking, but it is not suggest to use when welding the sheet metal. Otherwise, it will burn
out the workpiece easily. After ignition arc under some operation mode, the current should keep the
initial current, in order to heat up the workpiece or lighting.
Initial time (Hott):
it means the last time of the initial current, it is only valid in the S2T.
End time (Endt):
it means the duration of the end current, it is only valid in the S2T.
Spot time:
0.1
～
2s Spot welding time is the time of the SPOT TIG; it should be confirmed according to the
technological requirements.
Base current:
it is the base current of the PULSE TIG, the peak current is the set current
Duty ratio:
it is the ratio of the peak time and cycle in the Pulse TIG.
Frequency:
it is the frequency of the pulse TIG. These three parameters are for the PULSE TIG only, see the
diagram below:
Current curve of PULSE TIG
In the figure the I1 is initial current, IB is base current, IP is peak current(set current), I2 is end current. T1
is upslope time, T2 is downslope time. TP is the duration of the peak current, TB is the duration of the
base current, TP+TB is the pulse cycle, the pulse frequency is the c reciprocal of the cycle: 1/(TP+TB), the
duty ratio is the percentage of the duration of peak current in the pulse cycle: 100*TP/(TP+TB), changing
the pulse frequency and duty ratio could adjust the TP and TB value.
