Tungsten Inert Gas (Gtaw) Welding - Paton StandardMIG-160 Instruction Manual

This can also offer improved cooling rate control, affecting the weld's metallurgical
characteristics and lessening defect risks like porosity or cracks. By managing the current
and the resulting arc force, a significant reduction in spatter can be observed, leading to
cleaner welds and reduced post-weld cleaning. Moreover, when welding in challenging
positions, such as vertically or overhead, the pulsed current provides excellent molten pool
control, reducing the risks of sagging or molten metal dripping.
To implement this function in the device, you must first enable the current ripple mode
[Po.P], switch from the "OFF" state to the "ON" state, and also set four parameters: pulse
current [I.iP], pause current [I.PS ], pulse frequency [Fr.P] and pulse/pause ratio (or "duty
cycle") [dut].
By default, the ripple frequency [Fr.P] and duty cycle [dut] are at the most common values
of 5.0Hz and 50%, respectively. When the "duty cycle" parameter is changed from 50%, an
asymmetry is introduced between the current pulse time and the current "pause" time:
default
"duty cycle" [dut] = 50% "duty cycle" [dut] = 20% "duty cycle" [dut] = 70%
These parameters are set in different situations in different ways, according to the welder's requirements. See
paragraph 6.1 to change the value of any function in the current welding mode.
4. TUNGSTEN-ARC INERT-GAS WELDING (TIG)
ATTENTION: The most common protective gas used is pure argon "Ar", sometimes helium
"He", as well as a mixture of these in various proportions. Example: argon + helium "40% Ar
+ 60% He".
