Welding Preparation; Setup For Stick Welding (Smaw) - Forney EASY WELD 100 ST Manuel D'utilisation

Welding Preparation

An important factor in making a satisfactory weld is preparation. This includes studying the process and equipment
and practicing welding before attempting to weld finished product. An organized, safe, ergonomic, comfortable,
and well-lit work area should be prepared for the operator. The work area should specifically be free of all
flammables with both a fire extinguisher and a bucket of sand available.
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.
• 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, CUFF-LESS PANTS; HIGH TOPPED SHOES AND A
WELDING HELMET.

Setup for Stick Welding (SMAW)

• Switch the Process SELECTOR SWITCH (1) 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 (6 and 5) 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 (7).
• Set the amperage with the AMPERAGE ADJUSTMENT KNOB (4).
