Operational Suggestions
1. Wait four minutes before setting the ON/OFF switch to OFF after operation. This allows the cooling fans to
run to dissipate operating heat from the power supply.
2. For maximum parts life, do not operate the pilot arc any longer than necessary.
3. Use care in handling torch leads and protect them from damage.
4. When using water as the shield note the following:
