SERVICE MANUAL PEGAS 200 ACDC PULSE
WARNING NOTE Only trained personnel are permitted to work inside the machine. BEFORE OPENING THE MACHINE, CUT OFF ITS ELECTRICAL POWER BY REMOVING THE PLUG FROM THE MAINS SUPPLY SOCKET. Every six months, open the machine and clean it inside, using compressed dehumidified air. CAUTION. DO NOT USE COMPRESSED AIR AT TOO HIGH A PRESSURE. YOU COULD DAMAGE THE ELECTRONIC COMPONENTS. With the same frequency, check the welding cables and the supply cables. No modification, of any type, may be made to the welding machine.
Pro Vaši bezpečnost je nutné posečkat se sundáním krytu ze stroje po odpojení ze sítě po dobu minimálně 5 minut, kdy klesne napětí na kondenzátorech na hodnotu pod 36 V.
For safety while maintaining the machine, please shut off the supply power and wait for 5 minutes, until capacity voltage already drops to safe voltage 36V.

Sada 5.0198 obsahuje pouze dva piny. Pro zapojení různých druhů dálkového ovládání budete potřebovat více pinů. Viz schémata níže.
The set 5.0198 content two pieces of PINs. In order to connect different kinds of remote controls you will need order more PINs. See the schemas below.
Na plynovou hadici nasaďte dílec C Sešroubujte dílec A a B Nasaďte trn z dílce A do hadice Pevně utáhněte dílec B, tak, že vznikne mezera mezi osazením dílce A a dílcem B. Tím se zajistí hadice (viz obr. Níže).
Fit C onto the hose Screw A and B together Fit the nipple of A into the hose Firmly tighten B in the way that between A and B appears a gap. That way you fix the hose (see the image below)
