Converting a Duramax retrofit machine torch into a mini torch
You can convert a full-length machine torch to a mini-machine torch by removing the positioning sleeve. Refer to the figures
on the previous page while completing the following instructions.
Note: If you are converting a full-length machine torch to a mini-machine torch and mounting the torch at the same
time, skip this section and follow the instructions in the next section, “Mount the torch”.
1. Disconnect the torch lead from the power supply and remove the consumables from the torch.
Note: While disconnecting and reconnecting the torch parts, maintain the same orientation between the torch body
and torch lead. Twisting the torch body in relation to the torch lead can cause damage.
