Notable Features

Replacement Electrode for Model 300 Welder. The Electrode is 2.25 inches long.  The tip of the electrode should be clean and shaped into a sharp cone. When re-installing the tungsten electrode, use the depth gauge provided to place the tip about .020 inch from the end of a typical pair of thermocouple wires inserted in the wire holder.

ELECTRODE ADJUSTMENT

The rear of the instrument has a knob used to tighten the grip on the tungsten electrode. Rotating the knob counter -clockwise loosens the grip on the tung- sten rod so that it can be removed from the front of the instrument using a pair of needle-nose pliers. The tip of the electrode should be clean and shaped into a sharp cone. When re-installing the tungsten electrode, use the depth gage provided to place the tip about .020 inch from the end of a typical pair of thermocouple wires inserted in the wire holder.

PRECAUTIONS

The instrument is safe as long as a finger is not inserted into the weld cavity. The welding current initiates at the welding electrode and travels through the wires to the copper jaws to the welding cavity brass ring. Do not put a finger in this cavity. Insert only the holder that is provided as part of this equipment.

The model 300 thermocouple welder is used in conjunction with bottled argon gas which acts as the purging agent. Argon flows into the weld cavity and drives out oxygen so the welding of the thermocouple can take place in an inert environment.

Argon, inert gas, is not a dangerous substance. Bottled gas, however, is potentially hazardous since it is held in very high pressure. In addition, if large amounts of argon are released in a closed space, the normal atmosphere of 20% oxygen and 80% nitrogen can be driven out. Any personnel in a space where argon is leaking must leave immediately.

A Required safety precaution is to chain the argon bottle to the wall or to a workstation so that it cannot fall over. If there are any questions regarding operation or maintenance of the model 300 welder please contact our support team.
