Hypertherm Duramax Machine Torch main body 228716

This is a genuine Hypertherm 228716 plasma cutting torch body for Duramax mechanised cutting torches. This torch would have been fitted to the Hypertherm Powermax 65, 85 and 105 and used with a CNC plasma cutting table. 

Over time the threads on the torch body can become worn, which in turn does not allow the back cap that holds all the consumables in place is not able to be tightened properly. If the back cap is not tight  the micro switch is not actuated which gives Hypertherm error code 0-50. 

Changing the torch body is not too difficult, just follow the procedure below below, however we would advise to replace the mounting sleeve part number 228735 while stripping the torch down. The mounting sleeve can become very brittle over time and can easily break when being handled, see related products below.

Remove the torch body

1. Turn OFF the power and disconnect the torch lead from the power supply.

2. Remove the consumables from the torch.

3. If applicable, unscrew the strain relief body from the strain relief nut and slide the strain relief body back along the torch lead. (Part 8) 

4. If applicable, unscrew the strain relief nut from the positioning sleeve and slide the nut back along the torch lead.

5. Unscrew the positioning sleeve (Part 2) and coupler (Full-length machine torch) or coupler (Mini-machine torch) from the mounting sleeve.

6. Remove the three screws from the consumables end of the mounting sleeve using a #1 Phillips screwdriver and slide the mounting sleeve off the front of the torch body.

7. Disconnect the wire connector for the cap sensor micro switch (part1a).

8. Remove the cap sensor switch using a #1 Phillips screwdriver to remove the mounting screw. Set the screw and switch aside.

9. Remove the screw that secures the torch’s pilot arc wire to the torch body using a #1 Phillips screwdriver.

10. Loosen the nut that secures the gas supply line to the torch body using the 1/4-inch and 3/8-inch wrenches together (or two adjustable wrenches).

Discard the old torch body.

 1. Tighten the nut that secures the gas supply line to the torch body using the 1/4-inch and 3/8-inch wrenches together (or two adjustable wrenches).

2. Tighten the screw that secures the torch’s pilot wire to the torch body using a #1 Phillips screwdriver.

3. Install the cap sensor switch using a #1 Phillips screwdriver to tighten the mounting screw.
