be replaced.
Swirl Ring/Retaining Cap:
These should be replaced if broken, chipped, cracked or badly
heat damaged.
Tips and electrodes: These should wear reasonably evenly and it is normal practice to
replace them both together. If a new tip is inserted with a worn electrode the tip
will wear much more quickly than if the electrode was also replaced at that same time. If
tips or electrodes are wearing much faster than the other component it is likely to be caused
by one of the following: poor operator technique, incorrect air supply or damaged torch head.
It is also very important to only use genuine Strata consumables and parts for
the XT4000 torch. They are engineered to suit the machine and non-genuine items
may cause lack of performance, short life span, torch and machine damage and void
warranty.
§3.2 Installation & Operation
Electrical Connection
The CUT series is designed to operate on a 3 phase 380V AC power supply.
When the power supply voltage is over the safe work voltage, there are over voltage and
under voltage protection inside the welder, the alarm light will on, at the same time, the
current output will be cut off.
If the power supply voltage continually goes beyond the safe work voltage range, it will
shorten the welder life-span. The below measures can be used:

Change the power supply input net. Such as, connect the welder with the stable power
supply voltage of distributor;

Induce the machines using power supply in the same time;

Set the voltage stabilization device in the front of power cable input.
Compressed Air Requirements
A reliable and consistent supply of clean dry compressed air is essential for proper
operation. Although the machine contains its own internal air supply filtration system it is
recommended the compressed air supply should have external filtration in the line feeding
the machine, both a standard water trap (sintered bronze filter) and also a coalescing filter
(for oil in air).The air requirement
is a minimum of 120 l/min (4.5cfm) Free Air Delivery
