Quality Control Features
Weld Chamber |
Argon gas flowing through the weld chamber ensures a reliable, oxide-free weld. |
Firing Circuit |
Prestripped wire must be properly loaded into the handpiece and the handpiece correctly inserted into the weld chamber to initiate firing. |
Weld Fire Lockout |
Prevents poor welds caused by attempting a weld before the capacitors recharge. This condition exists immediately after a weld has been |
Line Voltage Regulator |
Maintains the capacitor bank voltage within ±0.25% of setting for a ±13% change in line voltage. This feature ensures consistent |
Line Failure Turndown |
Welder automatically activates the turndown circuit, discharging the capacitor bank when the line voltage is interrupted. This circuit en- |
Controls
Power Switch |
Disconnects both sides of the input power line when switched to the “OFF” position. |
Weld Ready |
Indicates that the capacitor bank has fully recharged and is ready to make a weld. |
Wire Gauge Selection |
Controls the level of stored energy necessary to make a thermocouple weld. Energy levels are indicated for each American Wire Gauge |

Capacitor Bank |
18,300 MFD ±10% at 20° C. Three capacitors are grouped in a single bank. At full rating, the capacitor bank is operated at 144 volts. |
Welding Speed |
As a manual feed thermocouple welder, the maximum number of welds per minute is determined by how fast the handpiece can be |
Argon Gas Flow |
Recommended flow rate is 3 cubic feet per hour. |
Argon Gas Shutoff |
Blocks the flow of argon gas to the weld chamber when line voltage is turned off. |
