Thank you for selecting WARPP brand inverter welding machine. In order to keep you safe away from unexpected accidents, and enjoy full benefits offered by our quality products during welding, please read the instruction in details prior to operation. Complying with procedures defined in this manual is always appreciated.
Usage & Features This Series Inverter Arc welding machines include 2 welding combinations: IN ARC (SMAW) & IN TIG (SMAW/TIG) with different specifications of rated current: 400A, 500A, 630A, etc., which are novelty high-efficient and energy-saving DC Arc welders, not only are used in carbon steel and low alloy steel welding, but also used in stainless steel, high alloy steel, copper, silver, molybdenum and titanium welding.

proper-sized copper wire. Please instruct the authorized electrician to connect the welder to power supply by using proper- sized, well-insulated copper wire. When operating in the damp, space limited area, must ensure well-insulated between body and work piece When operating in the high-rising location, must ensure safety by using safe net. Please power off the input voltage while no longer using.
Avoid being hurt by welding machine while in transport When moving the welding machine by fork-lift truck or crane, nobody can be allowed for standing downright the route of the moving welder, in case being hurt by the falling welding machine. The ropes or wires which used for hanging up the welding machine must be strong enough to withstand corresponding tension strength.
3. Installation The machines are portably designed, can be effortlessly moved by operators without fix-up. But it should be settled in even and dry places with well ventilation. 3.1 SMAW mode (1) Ensure firmly connection to welding cable. (2) Connect to remote controller( If needed) (3) Adjust every knobs, and switches on the front panel to proper position in line with selected mode.

This series welding machines apply IGBT soft switch inverter technology. 3- phase input volt are rectified by rectifier, inverted into HF AC, reduced by HF transformer, rectified and filtered by HF rectifier, then output DC power suitable for welding. After this process, the welder’s dynamical responsive speed has been greatly increased, so the welder size and weight are reduced noticeably result in energy saving.

(11) “Remote control/ TIG” cable socket It is used to connect with remote control cable to adjust welding current, arc force current or down-slope time through remote control box when it is on the “Remote control” mode, used to weld in extended distance. To weld in normal distance on TIG, it is used to connect TIG torch's control cable directly.
2.1.1 Shift between two working styles: (1) Shift from down-slope to non-down-slope Switch to “TIG” mode, pull TIG torch trigger, then loose it, open load voltage of power source will disappear to indicate working style being shifted to non-down-slope. (2) Shift from non-down-slope to down-slope Switch to “SMAW”...
