TIG welder teardown. ESAB TIG Caddy 1500i.
« on: June 04, 2019, 08:00:59 AM »

A teardown of a ESAB Caddy 1500i TIG welder, a run down of the current paths in the system and I show which parts I kept.

Datasheet on the unit: https://www.esab.dk/dk/da/products/arc-welding-equipment/tig-equipment-cc/industrial-equipment/caddy-tig-1500i-2200i-ta34.cfm

Dear,
I bought a welding machine Esab Caddy Arc201i from a scrap store, after my diagnostic I found the resistance R31 on the 15AP1 power board was blown, and the diode module 15D1 was missing on the secondary power board, after replacing the resistance R31 the machine switched ON and performed the initializing sequence. when  I measured the voltage at the T1 T2 pins of the 15TM1 transformer I found 0V. can you please help me on that? and regarding the diode module how can I fix that with local components if possible?
