To properly prepare for welding with your new welder, it is necessary to:
• Read the safety precautions at the front of this manual.
• Prepare an organized, well-lit work area.
• Provide protection for the eyes and skin of the operator and bystanders.
• Attach the ground clamp to the bare metal to be welded, making sure of good contact.
• Make sure that the wire-roller groove in the roller corresponds to the diameter and type of wire being used.
• Plug the machine into a suitable outlet.
• Completely open the gas cylinder valve. Adjust the gas pressure regulator to the correct flow rate. (Not applicable to
Stick “SMAW” process).
EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND SKIN.
PROLONGED EXPOSURE TO A WELDING ARC CAN CAUSE BLINDNESS AND BURNS. NEVER
STRIKE AN ARC OR BEGIN WELDING UNLESS YOU ARE ADEQUATELY PROTECTED. WEAR
FIRE RESISTANT WELDING GLOVES, HEAVY LONG SLEEVED SHIRT, CUFFLESS PANTS; HIGH
TOPPED SHOES AND A WELDING HELMET.
•
Press the Process SELECTOR BUTTON on the front panel to the left position.
•
Check the electrode packaging to determine the recommended polarity and connect the electrode holder and ground
clamp to the POSITIVE (+) and NEGATIVE (-) DINSE SOCKETS accordingly.
•
Direct current electrode positive (DCEP) or direct current reverse polarity (DCRP): electrode holder in POSITIVE (+)
DINSE SOCKET, ground clamp in NEGATIVE (-) DINSE SOCKET. Most electrodes use DCEP.
•
Direct current electrode negative (DCEN) or direct current straight polarity (DCSP): electrode holder in NEGATIVE (-)
DINSE SOCKET, ground clamp in POSITIVE (+) DINSE SOCKET
•
Ensure the ground clamp has a good connection to the workpiece and is connected on clean, bare metal (not rusty or
painted).
•
Secure the bare end of the welding electrode in-to the jaws of the electrode holder.
•
Switch the unit ON with the ON/OFF SWITCH
•
Set parameters with the SECONDARY PARAMETER KNOB/SELECTOR.
•
Set the amperage with the AMPERAGE ADJUSTMENT KNOB.
