Vertical up welding When welding vertical up with arc force on, the operator can control the amount of current by changing arc length, i.e. voltage. Weld metal is deposited by “digging” the electrode into the side of the base metal joint and then increasing the arc length with a flicking motion, to allow the weld pool to freeze, before digging the electrode into the other side of the base metal joint. Without arc force, increasing the arc length does not decrease the weld current sufficiently and the operator has to manually decrease the current via a remote current control to freeze the weld pool. This welding current reduction also reduces the penetration. The arc force allows the weld pool to freeze during the “flick” phase without decreasing the amount of weld current available during the “dig” phase thus maximizing penetration. 4.05 Weld Parameters Weld Parameter WELD (V) MIG Parameter Range Factory Setting 26 Incremental Unit STICK Weld Mode 10.0 to 36.0V DC 17.0V 0.1V INDUCTAN<strong>CE</strong> 0 to 100% 10% 1% HOT START 0 to 70A 20A 1A WELD (A) TIG or STICK 5 to 400A DC 80A 1A ARC CONTROL 0 to 100% 10% 1% 4.06 Power Source Features Table 6 – Weld Parameters Feature Description New Digital Control • All welding parameters are adjustable Touch Panel Switches • Touch switches eliminate mechanical damage Front Control Cover • Protects front panel controls Digital Meter Volt & Ammeter • Displays selected weld parameter value • Displays average weld current when welding • Displays average weld current for 20 seconds after weld has been completed • A selected weld parameter value can be adjusted at any time even while welding Intelligent Fan Control • The intelligent cooling system is designed to reduce dust and foreign material build-up, while providing optimum cooling. • Fan speed reduces approximately 30 seconds after machine is turned on • Fan speed increases when internal components reaches operating temperature ON/OFF Switch • Primary voltage Supply ON/OFF switch located on rear panel MIG LIFT TIG
Voltage Reduction Device (VRD) (shipped activated, field-capable) See Section 11 for de-activation instructions. Feature Description Reduces the OCV when the power supply is not in use. Eliminates the need for add on voltage reducers and has no effect on arc starting. • VRD fully complies to IEC 60974-1 • When Stick mode is selected the green VRD light is ON when not welding and red when welding. • When in TIG modes VRD is OFF. Control Knob • For the selected weld parameter, rotating the knob clockwise increases the parameter. • Rotating the knob counter-clockwise decreases the parameter. • A selected weld parameter value can be adjusted at any time even while welding. • Pushing the knob in sets the selected parameter then displays the next parameter. Self Diagnosis Using Error Codes • An error code is displayed on the Digital Meter when a problem occurs with Mains supply voltage or internal component problems. Save/Load Function • A total number of 5 programs can be saved into the 200AC/DC memory. SAVE the Current Weld Parameters into Memory • Press and HOLD the SAVE button. Beep will sound and Digital Meter display will show a number 1. • Select a memory location by rotating the control knob, 1 to 5 is displayed on the meter. After selecting the desired memory location (i.e. 1 to 5), press the right scroll button and the machine will give a beep to confirm the weld parameters are loaded onto the control panel. LOAD (retrieve) a Program to Control Panel • Press and HOLD the LOAD button. Beep will sound and Digital Meter display will show a number 1. • Select a memory location by rotating the control knob, 1 to 5 is displayed on the meter. After selecting the desired memory location (i.e. 1 to 5), press the right scroll button and the machine will give a beep to confirm the weld parameters are loaded onto the control panel. 27
