The local supply voltage must match the nominal voltage specified on the device. If the line voltage
fails, switch o the main switch and place the welding machine in the park position. EN 61000-3-11;
Zmax = 0.324Ω + j 0.202Ω. Consult electricity supply company if necessary.
If the device is being used on construction sites, a fault current circuit breaker must be used to
protect site personnel from electrical shock due to dampness and moisture.
There is a danger to life
from electric shock due to electrical voltage. The welding machine must therefore only be connect-
ed to sockets and extension cables with a protective earth conductor. Protect the welding machine
from moisture and wet conditions. Prior to commissioning, check the power cord, the plug, and the
extension cable for electrical and mechanical damage. The welding machine may only be opened by
instructed, qualified personnel.
Risk of fire and explosion
The welding machine can become an ignition source for fire and explosion. It must therefore not be
used near explosive gases or flammable materials. To avoid burning of the material to be welded,
please read the material safety data sheet from the material manufacturer. The welding machine must
only be used in the open or in a well-ventilated area.
Risk of burns
Do not touch hot wedge and surrounding parts when hot. Only touch the device at the handles and
operating units. Always allow the device to cool down.
Caution
Warning
1.1. Important safety instructions
Read through the operating instructions before commissioning for the first time.
In addition to the safety instructions contained in the individual sections of this instruction manual, the following
regulations must always be observed.
1. Application COMET 700/500
We recommend that you always keep the instruction manual with the device.
You can find more information on the COMET 700/500 and the myLeister app at www.leister.com
Congratulations on purchasing your COMET 700 or 500.
You have chosen a first-class hot-wedge welding machine.
It was developed and produced in accordance with the latest technology in the plastics-processing industry.
It has also been manufactured using high-quality materials.

Material Material thickness reference value Hot Wedge
PE-HD, PP 0.5 mm – 2.5 mm/ 20 mil – 100 mil Copper
PE-LD, TPO, FPO 0.5 mm – 3.0 mm/ 20 mil – 120 mil Copper
CSPE 0.5 mm – 2.5 mm/ 20 mil – 100 mil Steel
PVC-P 0.5 mm – 3.0 mm/ 20 mil – 120 mil Steel
Do not touch moving parts
There is a risk of inadvertently becoming caught and being pulled in. Do not wear loose articles of
clothing such as scarves or shawls. Tie up long hair or protect it by wearing headgear.
The device may only be operated under supervision as waste heat can reach flammable materials.
The device should also only be operated by trained specialists or under their supervision. Children are
not permitted to operate the device.
When welding, be aware of device hazards in the surrounding area, e.g., risk of tripping, risk of slip-
ping, strong sunlight, unattended equipment, etc.
1.3. Non-intended use
Additional materials upon request.
Material-specific properties can influence the welding capability.
Material types and thicknesses
1.2. Intended use
Any other use or any use beyond the type of use described is deemed non-intended use. In particular, the welding
of unintended materials.
The COMET 700/500 is intended for overlap welding of thermoplastic films and sealing sheets.
Only use original Leister spare parts and accessories; otherwise, any warranty and/or guarantee claims will be
invalidated.
Welding geometry
• The maximum overlap width of the lower and upper membranes is 125 mm.
• Welding seam widths 45 mm or 50 mm (depending on design).
• Welding seam with/without test channel (depending on version).

To lift the hot wedge welding machine manually, use
the handles (2) and the clamping lever (4).
Use the storage box supplied and the handle attached to the storage box to transport the hot wedge welding
machine.
The hot wedge (15) must have cooled down to at least 60°C/140°F before transport.
Never store flammable materials (e.g. plastic, wood) in the storage box!
Never use the handles (2) and the clamping lever (4) on the device or the handles on the storage
box for transport with the crane.
Comply with applicable national regulations regarding the carrying or lifting of loads.
The total weight of your COMET 700/500 including transport box is up to 14.5 kg (depending on the
version).

Check whether the hot wedge (15) is aligned centrally with the drive/pressure roller (11) (Figure 1). If this is not
the case:
• Loosen the three countersunk screws on the cable protection plate (Figure 2) and remove the cable protection
plate.
• Loosen the two cylinder screws on the wedge plate slightly (Figure 3). The cylinder screws do not have to be
completely loosened
• Align the hot wedge (15) so that it is in the middle of the drive/pressure roller at the bottom (11).
• Tighten the two cylinder screws on the wedge plate again (Figure 3).
• Reattach the cable protection plate with the three countersunk screws (Figure 2). Make sure that the cables of
the heating cartridges and the temperature probe are not pinched.
5.1. Checking the position of the hot wedge
5. Settings on COMET 700/500
Before the hot wedge is aligned with the welding machine, the device must be cooled down and the
main switch must be switched o. The power cord must have been disconnected from the power
supply.
Risk of crushing and shearing
When operating the clamping lever and clamping arm, there is a risk of injury to the hand. Always hold
the hot wedge welding machine by the handles and control units provided.
