Starting The Welding Process - WELDY booster EX2 Notice D'utilisation

Preparation for welding
• The handle (11) can alternatively be mounted left, right or bottom of the tool.
• Ensure the minimum cross-section when using extension cables. The extension cable must be approved for the
site of use (e.g. in the open air) and marked correspondingly. When using a power unit for power supply, it's
nominal power rating is: 2 x nominal power rating of the hand extruder.
Length Minimum cross-section (at ~230V)

Switching on
• Connect the WELDY hand extruder to the mains supply.
• Switch on the tool at the hot air blower switch (13).
• Adjust the hot air temperature by the air temperature potentiometer (12) to position 7.
In order to reach the operating temperature the tool needs to heat up
for at least 10 minutes.
Starting protection
The tool is equipped with current overload protection fuse (8). In case of too high current consumption,
the drive will switch o automaticaly if the material in the screw is insu ciently plasticized. Wait for 1
minute; press the overload protection fuse (8), the tool will re-start again.

Starting the welding process

• Fit the required WELDY welding shoe (1) according to the paragraph "change of the welding shoe".
• Welding can begin once the operating temperature has been attained.
Operate the tool drive on/o switch (10) for this purpose, operate the tool only when feed welding rod of 3 or
4 mm diameter into the welding rod opening (4) and allow a small amount plasticized material to escape.
• Adjust the heat of the tool until it reaches the ideal temperature to start the work.
