4.2 Description of controls

1. TIG2/TIG 4 switch - This control switches between 2s and 4s operation (normal and latch). In TIG2 position, when the
torch switch is pressed the arc ignites, when the switch is released the arc goes out. In TIG4 position, when the torch
switch is pressed and released the arc ignites, to extinguish the arc you must press and release the torch switch again.
2. TIG/MMA switch - This control switches the Viper's operating mode between MMA and TIG .
3. Slope up control - With the slope up control set to minimum the Viper will strike at the current set by the current con-
trol. With the slope up control set to anywhere but minimum the Viper will strike at 30A and then gradually increase the
current to the setting on the current control, the time this takes is determined by the position of the slope up control.
4. Current control - Adjusts the machines output current.
5. Remote control socket
switch for remote operation, plugging an external unit into the socket automatically selects remote operation and dis-
ables the internal current control.
6. Torch switch socket -
7. Gas out connector - This is a female quick coupling with an internal shut- off valve.
To connect, push the male connection on the end of the TIG torch adaptor into the coupling until you hear a click. To
fully disconnect, push the knurled ferrule on the connector inwards towards the Viper until it stops.
The shut off valve in the connector automatically closes when the connection is separated.
8. Digital Display - Indicates welding current in Amps, slope up, slope down and post gas times and also gives an indica-
tion when the machine is over temperature.
9. Slope down control - With the slope down control set to minimum the current will shut down immediately the torch
switch is released. With the slope down control set to anywhere but minimum and the torch switch released, the current
will gradually decrease from the setting on the current control to 5 amps, where the current will extinguish, the time this
takes is determined by the position of the slope down control.
