- Page 3 Ca u t i o n s Arc and arc rays may harm health. Arc welding can be hazardous. All performing welding workers ought to have health qualification that provided by authority organization. Protect yourself and others from possible serious injury or death. Keep children away. Pacemaker wearers should consult with their doctor before operating.
- Page 4 welding current is strong enough to damage them while having short circuit with them. Cylinder may explode if damaged. Make sure that the gas in the storage cylinder is qualified for welding, and the decompression flow-meter, the adapter and the pipe are all in good condition. Always keep cylinders in an upright position securely chained to an undercarriage or fixed support.
