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.

Hot wedge welding machine

Operating Manual (Translation of the Original User Manual)

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).
