I’ve been reading the manual for my new 2nd hand tig welder and it states the following:
Electrical conductors within 50 ft (15.2m) of the
welder should be enclosed in grounded rigid metallic
conduit or equivalent shielding, wherever possible.
Flexible metallic conduit is generally not suitable.
This is to reduce HF interference.
I have a large metal cupboard (6 foot high) located 1m away from the workbench. Does this mean I need to ground it with a non-flexible bar? I dont't see why a cable wouldn't do it.
Is HF interference really a big problem, also when welding 1.5mm steel (at low amperage)?
