Operation
11. Positive Control
The Positive button is used to plus selected in Programming sequence.
12. Negative Control
The Negative button is used to minus selected in Programming sequence.
13. Selecting Function Button
This button can select different programming parameter from No. 10
14. Negative Welding Terminal
Negative Welding Terminal. Welding current flows from the Power Source via heavy
duty bayonet type terminals. It is essential, however, that the male plug is inserted
and turned securely to achieve a sound electrical connection.
15. Shielding Gas Outlet
The Shielding Gas Outlet located on the front panel is a fast connection of a suitable
TIG Torch.
16. 5 Pin Control Socket
The 5 pin receptacle is used to connect a trigger switch or remote control to the welding
Power Source circuitry:
To make connections, align keyway, insert plug, and rotate threaded collar fully clockwise.
17. Positive Welding Terminal
Positive Welding Terminal. Welding current flows from the Power Source via heavy
duty bayonet type terminals. It is essential, however, that the male plug is inserted
and turned securely to achieve a sound electrical connection.
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug
being fused in the terminal.

Gas Pre-Flow
Absolute setting range 0.1s to 5s (0.1S increments)
This parameter operates in TIG modes only and is used to provide gas to the weld zone
prior to striking the arc, once the torch trigger switch has been pressed. This control is
used to dramatically reduce weld porosity at the start of a weld.

2.Initial Current
The main current Setting range 10AMP to 100AMP
This parameter operates in (4T) TIG modes only and is used to set the start current for TIG.
The Start Current remains on until the torch trigger switch is released after it has been
depressed.
Note: The maximum initial current available will be limited to the set value of the base
current.
3.Up Slope
Setting ranges :0.1S-10S (0.1S increments)
This parameter operates in (2T and 4T) TIG modes only and is used to set the time for the
weld current to ramp up, after the torch trigger switch has been pressed then released,
from Initial Current to High or base current.
4.Peak Current
Setting ranges
V1841: 10- 180A( DC TIG and AC HF TIG), 10- 170A(Stick mode)
This parameter sets the TIG WELD current. This parameter also sets the STICK weld
current.
5.Base Current
Setting ranges
V1841:10AMP to 180AMP (DC TIG mode), 10AMP to 180AMP (AC HF TIG mode)
Secondary current (TIG)/pulse pause current.
6.Pulse Width
Setting ranges 10%-90%
This parameter sets the percentage on time of the PULSE FREQUENCY for High weld
current when the PULSE is ON.
7.Pulse Frequency
Setting ranges 1HZ -200HZ
This parameter sets the PULSE FREQUENCY when the PULSE is ON.
8.Down Slope
Setting ranges 0.1-10s
This parameter operates in TIG modes only and is used to set the time for the weld current
to ramp down, after the torch trigger switch has been pressed to end current. This control
is used to eliminate the crater that can form at the completion of a weld.
9.End Current
Setting ranges 10A-180A
This parameter operates in (4T) TIG modes only and is used to set the finish current for TIG.
The end current remains ON until the torch trigger switch is released after it has been
depressed.
Note: The maximum crater current available will be limited to the set value of the base
current.
10. Post Flow
Setting ranges 1.0-10S
This parameter operates in TIG modes only and is used to adjust the post gas flow
