![]() The three terminals on this board support the flying leads from the transformer and choke where they are subject to bending otherwise when changing polarity. The fourth terminal, the electrode lead, I left flying, connected directly to the opposite polarity post from the work lead. This is printed circuit board base material without copper. I fixed the +, -, and work lead terminals to a piece of insulating glass fiber-epoxy sheet. Cebora Pocket 25Ī full price bridge may cost $3 to $5. The particular one I used, 12 Amps and 1000 volts, cost me $0.50 new at a local electronics surplus store. The bridge rectifier is readily available at low cost a wide range of specs (400 volts or more and 10 amps or more) is usable. I bit the bullet and added a bridge rectifier so that regardless of the work-electrode polarity, the motor controller always sees the same polarity. The motor speed control circuit needs raw DC in order to function since it has an SCR to switch. This seems to be a cost saving measure which complicates the polarity reversal modification. I traced out the circuit and I discovered the trigger switch connects to the electrode lead in the gun, rather than using a pair of wires to the switch independent of the electrode lead. Since this welder was intended for gas shielded use only and its low cost, there is no provision to reverse the polarity to DCEN for flux core, no gas welding. It came with a reel of flux core wire, too. It came with a regulator, but no gas tank. I was recently given a Cebora 833 Mig welder. ![]() Welding & Cutting / Download Automotive catalogue Concise (12 pages) catalogue of the Automotive line Approvals brochure Approvals by the car manufacturers Complete leaflet collection Leaflets of the single power sources Among the presentation pages of each single power source there is a 'Documentation.pdf' section in which you will also find the link to download the leaflet relevant to that product.
