1. Gas flow control
Adjusts the flow of gas to the welding torch, a flow rate of 15 to 20 lpm is normally used.
2 .Torch switch socket
For connecting the TIG torch control switch lead using a XLR type plug.
3. Torch switch socket
For connecting the TIG torch control switch lead using a DIN type plug.
4. Post gas time
This control sets the post gas delay, This is the period of time that the gas will continue flowing after the arc
has extinguished. The length of this period is determined by the position of the control.
5. Slope up control
With slope up control set to minimum the Viper will strike at current set by the current control. 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.
6. Current control
Use this on MMA and TIG to set the output current of the Viper.
7. Slope down control
Slope down control set to minimum the current will shut down immediately the torch switch is released.
Slope down control set to anywhere but minimum and torch switch released, the current will gradually
decrease from the setting on the current control to 5 amps, where the current will extinguish, time this takes
is determined by position of slope down control.
8. TIG/MMA switch
This control switches the Viper' s operating mode between MMA and TIG.
9. TIG2/TIG 4 switch
This control switches between 2T and 4T 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.
10. Digital Display
Gives an accurate indication of the welding current.
11. Power-on indicator
Indicates that the Viper is receiving power from the power source it is connected to.
12. Warning Indicator
Indicates that the Viper is connected in reverse polarity, i.e. the positive lead from the power source is
connected to the
negative in terminal on the rear of the Viper and vice-versa. The set will not operate in this condition.
