7. Preparations for welding
7.1 Power connection
The CPTX 400-2/400-2w/450-2w Synergy welder are equipped with a standard cable and
plug for 3x400V and 50Hz, and can be connected to any, for this voltage designed socket
contacts which are connected with appropriate protection.
7.2 Gas cylinder
Attach the gas cylinder with the chain at the rear of the unit. Now remove the cap and attach
the pressure regulator to the bottle so that no gas can escape. Then you have to attach the
hose and fix the connection with the nut bolt.
7.3 Setting up the torch
Connect the welding cable to the welding torch and the welding unit. Now tight the nut bolt.
For the water cooled torch you have to connect the water supply with the device as well
(Note the corresponding colors of the fast connectors). Then please connect the ground wire
with the welding device and fix the clamp with your workpiece.
At these welding machines it’s possible to connect also torches with a UP/DOWN function.
You can set up the correction of the wire feed speed with the digital switch on the welding
torch.
Important: When you connect an UP/DOWN torch, the device has to be turned off!
7.2 Wire spool
The wire spool must be attached on to the hub. Now tight the nut bolts and set up the
appropriate braking force. Make sure the correct direction of the wire!
7.3 Inching of the wire
To avoid potential problems during wire inching, the wire must be bent before the insertion.
Now, loose the spring by turning the screw slightly and separate the feed roller by the
pressure roller. Check if the selected feed roll matches the wire diameter. If this is not the
case, you have to flip over the feed roll. Then you have to push the wire through the two
roles into the liner (Button Pos.X4).
