The green button to the right of the unit is the START
button. Press this to begin the electro-fusion process and
timer.
The arrow (up and down) buttons are used to alter the
welding time displayed on the LCD display.
The LCD display will show various information
including the time selected and when welding, the time as
it counts down.

BASIC TECHNIQUES

Plug the unit into its power supply and switch the
supply ON.
The LCD will prompt the user to connect the output
leads to the fitting. Connect the leads ensuring a firm
positive connection is achieved.
The unit will then ask for the electrofusion time for
the particular joint. The time information will be found on
the joint, enter the value using the arrow buttons.

Finally, press the green START button to activate the
weld, the LCD will display elapsed time.
Once the weld is complete, allow the joint time to
cool correctly, based upon the information from the joint
manufacturer before disconnecting the output leads
and proceeding to the next joint.

EQUIPMENT CARE

Never push the equipment beyond its design limits.
If it will not do what you want with reasonable ease and
speed, assume you have the wrong type or size of welder
for the job. Ask at your local HSS Hire Weld Depot for
advice.
Keep the equipment clean. You will find this less of a
chore if you clean it up regularly rather than wait until the
end of the hire period.
When not in use, store the equipment somewhere
clean, dry and safe from thieves and unauthorised users.

FINISHING OFF

Switch OFF the power supply and unplug the unit.
Disconnect all leads and coil them up neatly ready
for return to your local HSS Hire Weld Depot.
