Tweco 100 Auto-Cut - Manuel (Page 54)

OPERATION 4-8 Manual 0-4764
Operational Suggestions
1. Wait five minutes before setting the ON/OFF switch to OFF after operation. This allows the cooling fan 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:
• Use clean drinking quality tap water to help prevent particulate build-up within the system water shield
plumbing.
• Particulate contamination and build-up can cause reduced consumable parts life and premature torch
failure.
• A cartridge type particulate water filter may help achieve optimum cutting performance.

These codes are for systems with Firmware versions 2.4 or later. If your system’s Firmware is a prior version,
contact your distributor for updates.
