General The options listed below are available with all power source variants.
Machine interface The machine interface connects the power source to the machine control. The following
signals can be transmitted across the machine interface:
Signal input: Start of welding / end of welding
- Signal input for a floating contact (sensor, relay, etc.) between pin X1:1 and pin X1:2
- The machine control signal input is processed by the power source in the same way
as a welding torch signal input. Ensure that the correct mode is set (2-step or 4-step)
- Use gold-plated contacts for optimum signal transmission
Signal output: Current flow signal
- Floating contact between pin X1:3 and pin X1:4
NOTE!
The machine interface isolates the welding circuit up to a maximum of 500 V DC.
To ensure reliable isolation from the welding circuit, use a relay with an insulation voltage
greater than 1500 V DC.
Gas test button The gas test button sets the protective gas flow. The protective gas flow is activated when
the gas test button is pressed and is deactivated after 30 seconds or if the button is pressed
again. The wire-feed unit remains inactive.
Gas preheater
CO2 connection
External gas preheaters for gas pressure regulators can be connected to the gas preheater
CO2 connection. Gas preheaters have a 36 V supply.
NOTE!
Voltage is only supplied to gas preheaters during welding operations.
The power of the gas preheaters must not exceed 150 W.
The gas preheater supply is protected against overloads and short-circuits.
