Gouging
The Powermax1100 can be used for gouging mild steel by using the optional gouging nozzle and
gouging shield.
•
Always wear full protection:
- A welding helmet with at least a #8 lens shade – Hypertherm recommends using a #10 lens
shade when gouging
- Welding gloves
- A welding jacket
The arc is fully exposed and will cause serious burns if the skin is not covered.
•
Install the gouging nozzle and shield the same as a standard cutting nozzle and shield. See
Changing Consumable Parts earlier in this section.
•
Adjust the air pressure to 60–65 psi (4.1–4.5 bar) with air flowing from the torch. Note that this
is lower than the cutting pressure.
•
Tilt the torch approximately 45
°
from the surface to be gouged and push the torch in the desired
direction. Multiple passes or "wearing" may be necessary to gouge wider and deeper sections.
