Weldy MINIWELDER GEO2 (154.880) [13/96] Error messages

•

The power voltage must correspond with the value given on the nameplate. Extension cords must have a

conductor cross section of minimum 3 x 1.5 mm2 with capacity not less than 10A. Conﬁ rm that external lines

have been well connected, check that the power switch is in the OFF position. Turn all temperature and speed

controls to the 0 position, open tension lever (6) to disengage pressure roller, then insert the plug.

•

Turn on the power and select temperature and speed, take 2 narrow pieces of material for welding trials.

Temperature selection can be di erent for the same material at di erent ambient temperature and material

thickness. To determine the best welding result, adjust the speed to approximately 2 m/min, and then make

di erent trial welds while slowly adjusting the temperature from low to high. (approximately 300 – 380 °C).

•

Evaluate welding parameters by carrying out tensile testing.

•

After temperature and speed have been determined, insert material to be welded between the two pressure

rollers, and engage the tension lever to start the welding process

•

Check the welded seam (welded bead/weld path). If required, correct the speed with potentiometer drive (12).

•

When welding is completed, disengage tension lever to prevent damage to the pressure rollers. Pressure rollers

should never run against each other without material between them.

•

Push On/O -button for heating and drive.

•

Allow device to cool-down.

•

Disconnect the mains voltage plug.

Perform a test welding according to the welding instructions of the material manufacturer and the

national standards or guidelines. Check the test welding.
