MAX200 UNDERWATER TORCH SUPPLEMENT
The MAX200 underwater torch assembly consists of the MAX200 hand torch and a torch
leads assembly that are permanently bonded together in the torch handle, The only
changeable parts in the torch are the consumable parts. Refer to the MAX200 instruction
manual 800870 for additional information on the MAX200 hand torch plasma arc cutting
system.
The remote start/stop switch is connected in a different configuration when used in
underwater cutting. The torch will fire only when the diver presses the torch switch and a
top-side operator activates the remote start/stop switch (at the diver's signal). This safety
switch configuration also enables top-side personnel viewing the cutting to deactivate the
torch start circuit if any potentially dangerous conditions arise that could harm the diver.
