1.6 WELDING CURVE
INV185PACDC is one of the most advanced TIG welders, because it offers you numerous
TIG functions with digital control. You can use the unit to set the complete welding ramp from
gas preflow and gas postflow time, current increase and decrease, pulse welding (pulse
current, pulse width, pulse frequency), AC frequency and AC balance in detail.
1. Gas pre-flow
The gas pre-flow time is the time during which an inert atmosphere is formed by the gas before the
welding process starts.
2. Start current
The set start current when starting the process.
3. Current increase – Upslope
The time in which the current is automatically increased.
4. Base current
5. Pulse current
6. Pulse width
Consists of the width time of the pulse and base current.
7. Pulse frequency
By setting the pulse frequency, you determine the time cycle in which the current changes between
pulse and base current.
8. Current reduction – downslope
The time in which the current is automatically lowered.
9. End current
The set final current at the end of the process.
10. Gas post-follow time
The gas post-follow time in which the torch and the workpiece are cooled after the welding process.
