The maximum machine pressure is factory set by adjusting a pressure relief valve located in the
pump.

Heater Plate
The 1400W, 240V, single phase aluminium heater plate has a cast in circular element to ensure
uniform heat distribution across the 240mm effective heating diameter.
Plate temperature is regulated by an electronic controller sealed inside the heater handle. LED’s
indicate when power is connected to the electric element. A dial thermometer indicates internal
plate temperature. (Refer section on heater technology.) It takes less than 15 minutes to heat up
to working temperature.
Replaceable non-stick cloths are fitted to the heater surfaces to eliminate hot plastic adhesion.
They are secured by snap rings enabling quick and easy field repair if the surface is damaged.
The detachable 1.8m electric cord has a high melting point outer sheath for protection against
short periods of accidental contact with the heater.
When not in use, the heater plate is stored in a protective floor stand it shares with the facer.
2.4.
Facer
The lightweight electric powered facing head is self aligning and will always produce parallel pipe
joint faces. Operating the variable speed motor at low speed will provide adequate torque and
speed to process small or large diameter pipes quickly. There is one blade on each cutting face
that will cut pipe from 225mm OD, to 45mm inside diameter.
2.5.
Reducing Liners
Each reducing liner set consists of 2 plain rings and 2 narrow rings. Each
ring is made up of 3 segments.
When welding pipe to pipe the plain rings are usually mounted in the
inner two clamps, with the narrow rings in the two outer clamps. The
narrow rings are for clamping short leg moulded fittings and must be
placed in the inner clamps when welding elbows.
The wide liners for 63mm, 75mm and 90mm nest inside 110mm wide
liners. All the narrow liner sizes fit directly into the main 225mm clamp.
Reducing liners can be manufactured to suit any pipe size from 200mm to
63mm, in either metric or imperial dimensions.
Note:
The HF225 is not able to hold 225mm short leg moulded elbows
or most short leg moulded Tees. Such fittings should be
purchased with long leg lengths to enable the Tee or elbow
section to protrude beyond the end clamp.
2.6.
Fittings Attachment
The fittings attachment tool is used when butt welding stub flanges or shouldered end fittings to
pipe. It is usually held in the inner 225mm main clamp on the hydraulic cylinder side. The tool
centrally locates flanges or shouldered ends quickly and accurately. It will securely hold the fitting
either by the outside or inside diameter depending on the fitting size.
2.7.
Accessory Cases
A steel accessory case provides storage for the heater, the facer, the heater floor stand, and up
to three sets of reducing liners.
Up to five additional liner sets may be stored in a separate steel carry case.
2.8.
High Pressure Welding
The EHF225 is not designed for high pressure welding. However the high pressure method may
be used providing the combined w drag pressure for a particular job falls within the range
of the fitted pressure gauge.
