PCB & Inverter Card Repair
Component-level board repair — before you write off the machine
A dead display or a machine that won't power on usually points to the control board or inverter card, not the whole machine. We repair at component level — tracing the actual failed part — which is often the difference between a small bill and buying new.
Inverter and control boards fail in predictable ways: blown MOSFETs or IGBTs, damaged driver ICs, failed capacitors, cracked solder joints from heat cycling. Rather than swapping the whole board (or the whole machine), we trace the fault to the actual failed component and replace it — keeping the repair cost proportional to the actual problem.
Not sure if you need this?
Signs your board or inverter card needs attention
- Machine is completely dead — no display, no fan, no response at all
- Intermittent power loss or cutting out mid-weld
- A replaced fuse blows again almost immediately
- Fault codes on the display that point to an internal error
- Visible burn marks, bulging capacitors or a burnt-component smell on opening the case

Common questions
FAQ
Is it worth repairing the board, or should I just buy a new machine?
In most cases, component-level board repair costs a fraction of a new machine. We'll tell you honestly if the damage is extensive enough that replacement makes more sense — we don't repair jobs that aren't worth it.
How long does a PCB or inverter card repair take?
Simple component failures are often fixed same day. Repairs needing a sourced part may take longer — we'll give you a timeline once the fault is traced.
Do you only replace the whole board, or actually repair it?
We repair at component level wherever possible — tracing and replacing the specific failed part rather than swapping the entire board.
