acArc puls XQ

The basic requirement for optimum welding results is the application-specific equipment of the
wire feed system. For the acArc puls XQ welding process, the entire wire feed system of the
Titan XQ AC series is factory-equipped with components for aluminium welding consumables!
Recommended system components:
• Power source of type Titan XQ 400 AC puls D
• Wire feeder of type Drive XQ AC
• Welding torch series of type PM 551 W Alu
Note the following equipment and setting features of the wire feed system:
• Wire feed rolls (set contact pressure depending on welding consumables and hose package
lengths)
• Central torch connection (use guide tube instead of capillary tube)
• Combined liner (PA liner with matching inner diameter for welding consumables)
• Use contact tips with forced contact
5.2.3

Welding torch connection

The Euro torch connector is factory-fitted with a guide tube for welding torches with steel liner. Conver-
sion is necessary if a welding torch with a steel liner is used!
• Operate welding torches with a liner > with a guide tube!
• Operate welding torches with a steel liner > with a capillary tube!
Depending on the wire electrode diameter or type, either a steel liner or liner with the correct inner
diameter must be inserted in the torch!
Recommendation:
• Use a steel liner when welding hard, unalloyed wire electrodes (steel).
• Use a chrome nickel liner when welding hard, high-alloy wire electrodes (CrNi).
• Use a plastic or teflon liner when welding or brazing soft wire electrodes, high-alloy wire electrodes or
aluminium materials.
Preparation for connecting welding torches with a spiral guide:
• Check that the capillary tube is correctly positioned in relation to the central connector!
